Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides an image processing method and device. The following are detailed below. The first embodiment,
The embodiment will be described from the perspective of an image processing apparatus, which may be specifically integrated in a terminal or the like, and the terminal may be specifically a mobile phone, a tablet computer, or a PC (personal computer) or the like.
An image processing method comprising: receiving an image processing request, the image processing request indicating an image that needs to be processed, the image including a plurality of icons; acquiring pixel points of the image according to the image processing request to obtain a pixel point set; searching an original icon boundary pixel point in the pixel point set, and expanding the original icon boundary of the icon according to a preset pixel interval and the original icon boundary pixel point so as to update the pixel point set; searching icon boundary pixel points in the updated pixel point set, and cutting out corresponding icons from the images according to the position information of the icon boundary pixel points in the images.
As shown in fig. 1b, a specific flow of the image processing method may be as follows:
101. an image processing request is received, the image processing request indicating an image that needs to be processed, the image including a plurality of icons.
The image in this embodiment may be a static image, i.e., a picture, and the icon may have various formats, for example, a PNG (portable network graphics) format, a BMP (bitmap) format, a JPEG (joint photographic experts group) format, and the like.
The Icon (Icon) may be any form of computer graphics, such as computer graphics with explicit meaning, for example, the Icon may be a desktop Icon (i.e. software identifier), an interface Icon (i.e. function identifier), or other graphic symbols with meaning, etc.
The image processing request may be triggered through a trigger interface such as a preset trigger key or an input box in the trigger terminal, for example, when a user clicks or slides an icon, the image processing request is triggered to be generated, at this time, the image processing apparatus may receive the image processing request, for example, the image processing request is received through a preset instruction receiving interface, and the like.
102. And acquiring pixel points of the image according to the image processing request to obtain a pixel point set.
The pixel point set comprises a plurality of pixel points, and the set can have various forms, such as an array form; specifically, pixel points of an image can be obtained according to an image processing request, so as to obtain a one-dimensional pixel array, wherein one array element in the one-dimensional pixel array can represent one pixel point; at this time, the one-dimensional pixel array is a pixel point set;
in order to facilitate image cutting and accelerate image cutting speed, the method can also convert the one-dimensional pixel array into a two-dimensional pixel array, and at the moment, the two-dimensional pixel array is a pixel point set; for example, a one-dimensional pixel array may be converted to a corresponding two-dimensional pixel array based on the size (width and height) of the image.
Optionally, in order to improve the graph cutting speed and the graph cutting accuracy, the method of this embodiment may cut the graph based on the effective pixel points, and at this time, the pixel point set may be an effective pixel point set, where the effective pixel point set includes a plurality of effective pixel points; that is, the step of obtaining the pixel point of the image according to the image processing request to obtain the pixel point set may include:
acquiring pixel points of the image according to the image processing request to obtain an original pixel point set;
determining effective pixel points and ineffective pixel points in the original pixel point set;
and determining a pixel point set according to the effective pixel point.
The effective pixel point can be a pixel point with a gray scale meeting a preset condition, for example, a pixel point with a gray scale level reaching the preset level or a gray scale value greater than a preset threshold can be determined as an effective pixel point, the ineffective pixel point is a pixel point with a gray scale not meeting the preset condition, for example, a pixel point with a gray scale value less than the preset threshold is determined as an ineffective pixel point, a transparent pixel point (with a gray scale value of 0) can be determined as an ineffective pixel point in actual application, and an opaque pixel point (with a gray scale value of 0) is determined as an effective pixel point; the preset conditions can be set according to actual requirements; that is, the step of "determining valid pixel points and invalid pixel points in the original pixel point set" may include:
and determining effective pixel points and ineffective pixel points in the original pixel point set according to the gray scale corresponding to the pixel points in the original pixel point set.
In practical application, in order to facilitate the image cutting and improve the image cutting speed, a first pixel identifier may be set for an effective pixel and a second identifier may be set for an ineffective pixel to distinguish the pixels, for example, the effective pixel is marked with a bit 1, and the ineffective pixel is marked with a bit 0.
Optionally, in order to meet the actual demand for cutting a graph, the flexibility of cutting a graph is improved, for example, a picture including at least two icons is cut from an image, a protection region may be allowed to be set between the two icons in this embodiment, and the protection region is not cut when the graph is cut, that is, after the step "determining an effective pixel point and an ineffective pixel point in the original pixel point set", the step "determining a pixel point set according to the effective pixel point" in this embodiment may further include:
determining whether the image is provided with a protection area;
and if so, determining the invalid pixel points in the protection area as valid pixel points.
In this embodiment, under the condition that the identification is set for the valid pixel and the invalid pixel, the invalid pixel can be determined as the valid pixel by changing the identification of the invalid pixel, that is, the step "determining the invalid pixel located in the protection area as the valid pixel" can include: and changing the second pixel identification of the invalid pixel point in the protection area into the first pixel identification so as to determine the invalid pixel point as an effective pixel point. For example, the flag 0 of the invalid pixel point in the protection area is changed to 1.
103. And searching the original icon boundary pixel points in the pixel point set, and expanding the original icon boundary of the icon according to a preset pixel interval and the original icon boundary pixel points.
The original icon boundary pixel point may be a pixel point corresponding to the original boundary of the icon.
Optionally, in order to distinguish the pixel points and facilitate the image cutting, in this embodiment, after the original icon boundary pixel points of the icon are searched in the pixel point set, an identifier may be set for the original icon boundary pixel points, specifically, a third pixel identifier is set for the original icon boundary pixel points, for example, the original icon boundary pixel points are marked as 2.
Considering that an icon may include multiple sub-icons that are independent and separate from each other, and thus may have multiple boundaries, if the icon is cut based on only the original icon boundary pixel points, the icon may be cut into multiple icons, and the accuracy of the cut is relatively poor, for example, referring to fig. 1c, the "footprint" icon has four original icon boundaries, and if the icon is cut based on the original icon boundaries directly, the "footprint" icon may be cut into four icons, and it is obvious that the cut is wrong; in order to overcome the foregoing problems and improve the accuracy of the graph cutting, the present embodiment may expand the boundary of the original icon to fill the space between the sub-icons, and then cut the graph based on the expanded boundary; that is, after searching for the original icon boundary pixel point, the present embodiment may also expand the original icon boundary of the icon according to the preset pixel interval and the original icon boundary pixel point.
The preset pixel interval is a boundary extension distance represented by a pixel, such as 10 pixels, 5 pixels, and the like. The preset pixel interval can be set according to actual requirements. Optionally, there may be a plurality of manners for obtaining the preset pixel interval, for example, when the image processing request carries the preset pixel interval, the preset pixel interval may be obtained from the image processing request, or for example, the preset pixel interval may be obtained from a storage unit based on the image processing request.
Specifically, the step of "expanding the original icon boundary of the icon according to the preset pixel interval and the original icon boundary pixel point" may include:
drawing a corresponding original icon boundary according to the original icon boundary pixel points;
and extending the original icon boundary outwards according to the preset pixel interval, wherein the distance between the extended icon boundary and the original icon boundary is equal to the preset pixel interval.
The distance between the boundary of the extended icon and the boundary of the original icon refers to a line distance between the boundary line of the extended icon and the boundary line of the original icon, and the line distance may be defined as a shortest distance between two non-intersecting lines.
For example, referring to fig. 1d, the original icon boundary of the "footprint" icon may be expanded based on 10 pixel points, where a distance d between the expanded icon boundary line and the original icon boundary line is 10 pixel points; as shown, after the original icon boundaries of the "footprint" icon are expanded, the spaces between sub-icons in the "footprint" icon are filled.
Optionally, the method for depicting the boundary of the original icon in this embodiment may be various, for example, the original icon boundary pixel points belonging to the same original icon boundary may be obtained to obtain the original icon boundary pixel point set, and then the corresponding icon boundary is depicted based on the original icon boundary pixel point set. The original icon boundary pixel points belonging to the same icon boundary can be obtained based on the interval or distance between the original icon boundary pixel points.
104. And updating the pixel point set according to the expanded result.
Specifically, after the boundary of the original icon is expanded, the pixel point set may be updated based on the result of the expansion of the boundary, for example, a pixel point on the boundary of the expanded original icon may be determined in the pixel point set according to the expanded result, and then, the attribute information of the pixel point may be changed to update the pixel point set, such as changing the pixel point identifier, the gray scale value, and the like. 105. Searching icon boundary pixel points in the updated pixel point set, and cutting out corresponding icons from the images according to the position information of the icon boundary pixel points in the images.
For example, after the original icon boundary is expanded, icon boundary pixel points can be searched in the updated pixel point set again, fourth pixel identifiers are set for the icon boundary pixel points, so that the icon picture containing the icon is cut conveniently, for example, the icon boundary pixel points are marked as 3, and then the icon picture containing the icon is cut according to the position information of the icon pixel points in the image.
The position information of the icon boundary pixel point in the image may include: and (3) cutting out the corresponding icon from the image according to the two-dimensional coordinate value of the icon boundary pixel point.
Specifically, the step of "cutting out a corresponding icon from the image according to the position information of the icon boundary pixel point in the image" may include:
determining icon boundary pixel points belonging to the same icon boundary to obtain a boundary pixel point set corresponding to the icon boundary;
acquiring position information of the boundary pixel points of the image in the boundary image point set in the image;
and cutting the icon from the image according to the position information.
In the embodiment of the method, after the icon boundary pixel points are found, the icon boundary pixel points belonging to the same or the same icon boundary are determined to obtain the boundary pixel point set corresponding to the icon boundary, and specifically, the icon boundary pixel points belonging to the same or the same icon boundary are determined according to the interval between the icon boundary pixel points; for example, icon boundary pixel points belonging to the same or same icon boundary may be determined based on the interval or pitch between adjacent icon boundary pixel points; because the icon boundary pixel points belonging to the same icon boundary are all continuous, and the interval between the adjacent icon boundary pixel points is smaller than a preset threshold, a certain icon boundary pixel point can be used as a starting point, then the adjacent icon boundary pixel points with the interval smaller than the preset threshold are searched, then the icon boundary pixel points with the interval smaller than the preset threshold are searched, … … is analogized, and the icon boundary pixel points belonging to the same icon boundary can be searched.
In an actual situation, generally, an interval between two adjacent icon boundary pixel points on the same icon boundary is zero, that is, the two adjacent icon boundary pixel points are connected, so that in this embodiment, one icon boundary pixel point, which is marked as a, can be found first, then the adjacent icon boundary pixel point connected to the icon boundary pixel point is found, which is marked as a, then other icon boundary pixel points of the adjacent icon boundary pixel points are obtained, which is also marked as a, … … and so on, and all icon boundary pixel points corresponding to a certain icon boundary a can be obtained, that is, a boundary pixel point set corresponding to the icon boundary a is obtained.
For example, when all the icon boundary pixels are marked as 3, the icon boundary pixels can be traversed, when one icon boundary pixel (such as the icon boundary pixel which is encountered for the first time) is encountered, all the icon boundary pixels 3 which belong to the icon boundary corresponding to the icon boundary pixel 3 are marked as 3+1, namely 4, so as to obtain a boundary pixel set corresponding to the icon boundary 4, specifically, all the icon boundary pixels of the boundary can be marked as 4 by searching the icon boundary pixel which is connected with the icon boundary pixel, so as to obtain a boundary pixel set corresponding to the icon boundary 4, wherein the boundary pixel set comprises the icon boundary pixels marked as 4; after marking is completed, when icon boundary pixel points of a new icon boundary are encountered, all icon boundary pixel points of the new icon boundary are marked as 3+1+1, namely 5, so as to obtain a boundary pixel point set corresponding to the new icon boundary 5, and by analogy, boundary pixel point sets corresponding to icon boundaries 6, 7, 8 … … and the like can be obtained.
The icon can be cut according to the position information of the icon boundary pixel points in various ways, for example, an icon cutting area can be determined on an image according to the position information of the icon boundary pixel points, and then the corresponding icon is cut based on the icon cutting area.
In order to improve the accuracy of the graph cutting and save system resources, in this embodiment, the icon may be cut based on the actual position information of the icon boundary pixel point, that is, the icon is cut according to the actual size of the icon, and the step "cutting the icon from the image according to the position information" may include:
acquiring position offset information corresponding to the preset pixel interval;
acquiring actual position information of the image boundary pixel points in the image in the boundary image point set according to the position offset information and the position information;
and cutting the icon from the image according to the actual position information.
In this embodiment, an icon may be directly cut from an image according to actual location information of an icon boundary pixel point in a boundary image point set in the image, for example, an icon cutting area or an outline may be determined according to the actual location information of the icon boundary pixel point in the boundary image point set in the image, then, cutting may be performed based on the icon cutting area or the outline, or size information (width, height, etc.) corresponding to the icon may be obtained according to the icon boundary pixel point, then, cutting may be performed based on the actual location information and the size information, that is, "cutting the icon from the image according to the actual location information" may include:
acquiring size information corresponding to the icon according to actual position information of the boundary pixel points of the icon in the boundary pixel point set;
and cutting the icon from the image according to the size information and the actual position information.
For example, an icon cutting region may be determined according to the size information of the icon and the actual position information of the icon boundary pixel point, and then a corresponding icon is cut from the image according to the icon cutting region. In practical applications, the icon may be cut out from the image by using canvas of hypertext Markup Language (HTML), such as HTML5, in combination with the size information and the actual position information.
For example, referring to fig. 1e, taking an image including four icons as an example, by applying the image processing method of the present embodiment, a picture is cut according to the actual size of the icon, and finally four icon pictures are cut, where each icon picture includes one icon, and the size of the icon picture is adapted to the size of the icon included in the icon picture, that is, the width and height of the icon picture are equal to the width and height of the icon included in the icon picture.
As can be seen from the above, when an image processing request is received, the embodiment of the present invention may obtain a pixel point of the image according to the image processing request, to obtain a pixel point set, then search for an original icon boundary pixel point in the pixel point set, expand an original icon boundary of an icon according to a preset pixel interval and the original icon boundary pixel point, update the pixel point set according to the expanded result, search for an icon boundary pixel point in the updated pixel point set, and cut out a corresponding icon from the image according to position information of the icon boundary pixel point in the image; according to the scheme, the image can be cut based on the position information of the boundary pixels of the icon in the image, namely, the image can be cut according to the actual size of the icon, and the user does not need to adjust the position of the image and other operations during image cutting, so that the image cutting operation is simplified and the image cutting efficiency can be improved compared with the prior art; in addition, because the scheme can cut the graph according to the actual size of the icon, the accuracy of the graph cutting can be improved, and system resources can be saved.
Example II,
The method described in the first embodiment is further illustrated by way of example.
In the present embodiment, the image processing apparatus will be described by taking as an example that the image processing apparatus is integrated in a terminal.
The image processing device can be integrated in the terminal in the form of software, for example, can be integrated in the terminal browser in the form of software, and the like.
As shown in fig. 2a, a specific flow of an image processing method may be as follows:
201. the terminal receives an image processing request indicating an image that needs to be processed, the image including a plurality of icons.
In this embodiment, the image to be processed may be a static image, i.e., a picture, and the icon may have various formats, for example, a PNG (portable network graphics) format, a BMP (bitmap) format, a JPEG (joint photographic experts group) format, and the like.
The Icon (Icon) may be any form of computer graphics, such as computer graphics with explicit meaning, for example, the Icon may be a desktop Icon (i.e. software identifier), an interface Icon (i.e. function identifier), or other graphic symbols with meaning, etc
The image processing request may be triggered by a trigger interface such as a preset trigger key or an input box in the trigger terminal, for example, when a user clicks or strokes an icon, the image processing request is triggered to be generated.
Referring to fig. 2b, taking an example of a picture 20 including a plurality of icons, the picture 20 may be an Icon aggregate graph, and after uploading the Icon 20 to a terminal browser, a user may set a pixel interval in advance by moving a slider 21 on a sliding rail 22, so as to expand a boundary based on the pixel interval in a graph cutting process, as shown in fig. 2b, the pixel interval is set to 20px, that is, 20 pixels; when the user clicks the "map cutting button" 23 in the map cutting interface, the terminal browser is triggered to generate an icon processing request, and at this time, the image processing apparatus in this embodiment may receive the image processing request.
In order to meet the user's requirements for cutting a map and improve the flexibility of cutting the map, for example, a picture including at least two icons is cut from the image, the embodiment may set a protection area, as shown in fig. 2b, a protection area setting button 24 is provided in the map cutting interface, if the user wants to cut an icon image including a "shopping cart" and a "business card", the user may click the button 24, and then the user may set a protection area on the picture 20 (e.g., select the protection area by a frame selection), for example, the area indicated by a dashed box 25 in fig. 2b may be selected as the protection area; in this embodiment, the protection area is not cut off, and when an area between two adjacent icons is selected as the protection area, an icon picture including the two adjacent icons can be cut off.
202. And the terminal acquires the pixel points of the image according to the image processing request to obtain an original pixel point set, and determines effective pixel points and ineffective pixel points in the original pixel point set.
Specifically, for convenience of map cutting, the identifiers may be set for the valid pixel points and the invalid pixel points, for example, the valid pixel points are marked as 1, and the invalid pixel points are marked as 0.
In this embodiment, the valid pixel points and the invalid pixel points may be determined based on gray scales corresponding to the pixel points, for example, the pixel points whose gray scale levels reach a preset level or whose gray scale values are greater than a preset threshold may be determined as the valid pixel points, and the invalid pixel points are determined as the pixel points whose gray scales do not satisfy the preset condition, and so on.
203. The terminal determines whether the icon has a protection area, if so, step 204 is executed, and if not, step 205 is executed.
204. And the terminal determines the invalid pixel points in the protection area as valid pixel points.
For example, the invalid pixel points in the dashed line frame in fig. 2b may be determined as valid pixel points. Under the condition that the pixel point is provided with the identification, the invalid pixel point can be determined to be the valid pixel point through the identification change of the pixel point, for example, the mark 0 of the invalid pixel point in the protection area is changed into 1.
205. And the terminal determines a pixel point set according to the effective pixel points and searches the boundary pixel points of the original icon in the pixel point set.
The original icon boundary pixel point may be a pixel point corresponding to the original boundary of the icon.
Optionally, in order to distinguish pixel points and facilitate graph cutting, in this embodiment, after an original icon boundary pixel point of an icon is found in the pixel point set, an identifier may be set for the original icon boundary pixel point, specifically, a pixel identifier is set for the original icon boundary pixel point, for example, the original icon boundary pixel point is marked as 2.
206. And the terminal expands the original icon boundary of the icon according to the preset pixel interval and the original icon boundary pixel point, and updates the pixel point set according to the expansion result.
Considering that an icon may include a plurality of sub-icons that are independent and separated from each other, and therefore may have a plurality of boundaries, if the icon is cut based on only the pixels on the boundary of the original icon, which may result in cutting the icon into a plurality of icons, the accuracy of the cut icon is relatively poor, and the accuracy of the cut icon is improved, this embodiment may expand the boundary of the original icon to fill the space between the sub-icons, and then cut the icon based on the expanded boundary.
Specifically, the step "the terminal expands the original icon boundary of the icon according to the preset pixel interval and the original icon boundary pixel point" may include:
drawing a corresponding original icon boundary according to the original icon boundary pixel points;
and extending the original icon boundary outwards according to the preset pixel interval, wherein the distance between the extended icon boundary and the original icon boundary is equal to the preset pixel interval.
The distance between the boundary of the extended icon and the boundary of the original icon refers to a line distance between the boundary line of the extended icon and the boundary line of the original icon, and the line distance may be defined as a shortest distance between two non-intersecting lines.
In this embodiment, the preset pixel interval may be a boundary extension distance represented by a pixel point. The preset pixel interval can be set according to actual requirements, such as 10 pixel points, 5 pixel points and the like; for example, referring to fig. 2b, the user can set the pixel interval in advance by moving the slider 21 on the slide rail 22, and the pixel interval is set to 20 pixels in the figure.
207. And the terminal searches the icon boundary pixel points in the updated pixel point set, determines the icon boundary pixel points belonging to the same icon boundary, and obtains a boundary pixel point set corresponding to the icon boundary.
For convenience of cutting the graph, the terminal of this embodiment may also set a pixel identifier for the icon boundary pixel, for example, mark the icon boundary pixel as 3.
Specifically, the method of the embodiment may determine the icon boundary pixel points belonging to the same or the same icon boundary after finding the icon boundary pixel points, to obtain a boundary pixel point set corresponding to the icon boundary, and specifically, may determine the icon boundary pixel points belonging to the same or the same icon boundary according to the interval between the icon boundary pixel points; for example, icon boundary pixel points belonging to the same or the same icon boundary may be determined based on the interval or pitch between adjacent icon boundary pixel points.
In practical application, generally, the interval between two adjacent icon boundary pixel points on the same icon boundary is zero, that is, the two adjacent icon boundary pixel points are connected, so that in this embodiment, one icon boundary pixel point can be found first, and then, all boundary pixel points belonging to the same icon boundary can be obtained by finding the connected boundary pixel points.
For example, when all the icon boundary pixels are marked as 3, the icon boundary pixels can be traversed, when one icon boundary pixel (such as the icon boundary pixel which is encountered for the first time) is encountered, all the icon boundary pixels 3 which belong to the icon boundary corresponding to the icon boundary pixel 3 are marked as 3+1, namely 4, so as to obtain a boundary pixel set corresponding to the icon boundary 4, specifically, all the icon boundary pixels of the boundary can be marked as 4 by searching the icon boundary pixel which is connected with the icon boundary pixel, so as to obtain a boundary pixel set corresponding to the icon boundary 4, wherein the boundary pixel set comprises the icon boundary pixels marked as 4; after marking is completed, when icon boundary pixel points of a new icon boundary are encountered, all icon boundary pixel points of the new icon boundary are marked as 3+1+1, namely 5, so as to obtain a boundary pixel point set corresponding to the new icon boundary 5, and by analogy, boundary pixel point sets corresponding to icon boundaries 6, 7, 8 … … and the like can be obtained.
208. The terminal obtains the position information of the boundary pixel points of the icon in the boundary image point set in the image and the position offset information corresponding to the preset pixel interval, and obtains the actual position information corresponding to the boundary pixel points of the icon according to the position offset information and the position information.
