As described above, the image adjustment may perform restoration processing on a damaged image, and causes of image damage include: the image processing method is used for solving the problem that the efficiency of adjusting the image by the user is low in the prior art, and the image processing method can be used for quickly adjusting the image.
The image processing method disclosed in the present disclosure may be executed by a terminal device, where the terminal device may be a mobile terminal or a desktop terminal, please refer to fig. 1, and the method specifically includes the following steps:
s101, acquiring an image to be adjusted;
the terminal device obtains the initial image, and may use the initial image as an image to be adjusted, or after obtaining the initial image, the terminal device may further process the initial image to obtain the image to be adjusted, and a specific processing manner will be described in an embodiment later.
In this embodiment, the terminal device may obtain the initial image from the local database, and may also receive the initial image sent by the server.
Step S102, when the adjustment operation of a user on a repair line for adjusting an image is detected, determining the position information of the adjusted repair line on the image based on the adjustment operation;
when the terminal device detects an adjustment operation of a user on a repair line for adjusting an image, the position information of the adjusted repair line on the image can be determined based on the adjustment operation, and the repair line is preset.
In this embodiment, one possible case that the terminal device detects the adjustment operation of the repair line by the user is: when the terminal equipment can detect the selection operation of a user on the repairing wire display control, the terminal equipment calls the repairing wire and displays the repairing wire on a terminal display interface (or sets the repairing wire to be in a usable state, but hides the repairing wire and prompts the using mode of the repairing wire to the user), so that the user can conveniently adjust the repairing wire;
another possible scenario is: the repairing wire is displayed on the terminal display interface (or the repairing wire is set to be in a usable state by the terminal equipment, but the repairing wire is hidden, and the using mode of the repairing wire is prompted to a user), so that the user can adjust the repairing wire.
In this embodiment, the multi-line may be understood as a picture repairing tool in the terminal device, and the adjustment operation of the user on the repairing line includes adjusting the position of the repairing line, or includes adjusting the position and the angle of the repairing line.
The position information of the repair line on the image in the present embodiment may be coordinate information of the repair line on the picture determined by taking the picture as a coordinate system.
Step S103: determining a region to be adjusted of the image based on the position information;
the terminal device may determine the area to be adjusted of the image based on the position information of the repair line, where a specific determination manner will be described in an embodiment later, and it should be noted that the area to be adjusted may be a rectangular area.
Step S104: determining a reference line corresponding to the adjusted repair line;
the reference line is used as a reference line when the first image is adjusted, the terminal device determines a reference line corresponding to the adjusted repairing line from at least two preset reference lines, and the reference line is determined based on the angle of the adjusted repairing line and is generally parallel to the adjusted repairing line.
It should be noted that, if the user adjusts the repair wire only to adjust the position of the repair wire, the adjusted repair wire herein refers to the repair wire after the position adjustment, and in this case, the adjusted repair wire may be replaced by the repair wire before the adjustment; if the user adjusts the repair wire, namely, the position and the angle of the repair wire are adjusted, the adjusted repair wire can refer to the repair wire after the position and the angle are adjusted, or only refer to the repair wire before the angle is adjusted;
step S105, adjusting the first image in the area to be adjusted of the image based on the reference line.
The terminal device can adjust the first image in the area to be adjusted of the image based on the reference line to realize the restoration of the first image.
In this embodiment, after the image to be adjusted is determined, if it is detected that a user performs an adjustment operation on a repair line for adjusting the image, the position information of the adjusted repair line on the image may be determined based on the adjustment operation, so as to determine the area of the image to be adjusted based on the position information.
Optionally, in this embodiment, for two possible cases that the terminal device detects an adjustment operation of a user on the repair line, a manner of adjusting the repair line by the user includes the following possible cases:
if the user needs to operate the repair wire to adjust the repair wire, for example, the user may adjust the repair wire by pulling the repair wire, the method for the user to adjust the repair wire includes:
case 1: if the number of the repair lines is one, a user can firstly adjust the repair lines to the repair lines in the preset direction (if the repair lines are the repair lines in the preset direction, the direction of the repair lines does not need to be adjusted again), and then the position of the repair lines is adjusted based on the repair lines after direction adjustment;
case 2: if the number of the repair lines is one, a user can firstly adjust the position of the repair line and then adjust the repair line after the position adjustment to the repair line in the preset direction (if the repair line after the position adjustment is the repair line in the preset direction, the direction of the repair line does not need to be adjusted again);
in the above cases 1 and 2, the repair line after direction adjustment may be a repair line parallel to the length direction of the image, or a repair line perpendicular to the length direction of the image;
referring to fig. 2, one possible scenario is: the user clicks a 'repairing line' button, an initial repairing line is displayed in a terminal display page, the terminal equipment can adjust the angle of the repairing line to be longitudinally parallel to the image based on user operation, and when the terminal equipment detects that the user pulls the repairing line to a certain position in the image rightwards, the repairing line can be adjusted to the position, and the position is the adjusted repairing line.
Case 3: if the number of the repair lines is at least two, for example, the number of the repair lines is two, and the repair lines are the repair line in the first preset direction and the repair line in the second preset direction, respectively, the user may select the repair line in the first preset direction or the repair line in the second preset direction to operate based on the requirement, the repair line in the first preset direction may be the repair line parallel to the length direction of the image, and the repair line in the second preset direction may be the repair line perpendicular to the length direction of the image, in this case, the user does not need to adjust the angle of the repair line.
In case 3, the prompt information that the terminal device prompts the user of the repairing line using mode may be: the user may be prompted in the form of text information, such as "pull lines from here", or in the form of dynamic images or pictures, such as prompting the user in the form of dynamic images to pull lines from the terminal display page in the length direction, or prompting the user in the form of dynamic images to pull lines from the terminal display page in the width direction.
Referring to fig. 3, one possible scenario is: the user clicks a 'repairing line' button, an initial repairing line is displayed in a terminal display page and comprises the repairing line in the transverse direction of the image and the repairing line in the longitudinal mode of the image, when the terminal equipment detects that the user pulls the repairing line in the transverse direction to a certain position in the image rightwards, the repairing line can be adjusted to the position, and the position is the position of the adjusted repairing line.
Referring to fig. 4, one possible scenario is: the user clicks a 'repairing line' button, the terminal display page prompts the user to adjust the repairing line in a picture mode, the user can select to pull the repairing line from the transverse direction of the image or pull the repairing line from the longitudinal direction of the image, and when the terminal equipment detects that the user pulls the repairing line in the transverse direction of the image to a certain position in the image rightwards, the repairing line can be adjusted to the position, wherein the position is the position of the adjusted repairing line.
If the user does not need to operate the repairing wire, the repairing wire can be adjusted, for example, the user adjusts the repairing wire in a mode of drawing a transverse line or a longitudinal line in a preset area of a picture, and the mode of adjusting the repairing wire by the user includes:
case 4: when the terminal device detects that a user draws a transverse line or a longitudinal line in a preset area of a picture (when the user draws the line, the terminal device can synchronously correct the line drawn by the user), the terminal device detects that the user adjusts the repairing line used for adjusting the image, so that the terminal sets the line drawn by the user, adjusts the initial repairing line in the terminal device, and the line drawn by the user is used as the adjusted repairing line.
In this embodiment, the manner of synchronously correcting the lines by the terminal device is to correct the horizontal lines drawn by the user into lines parallel to the length direction of the picture, and to correct the longitudinal lines drawn by the user into lines perpendicular to the length direction of the picture.
In this embodiment, the prompt information that the terminal device prompts the user of the repairing line using mode may be: the user may be prompted with a character message, for example, "the repair line is drawn here", or with a moving image, for example, the user may be prompted with a moving image to draw the repair line.
Referring to fig. 5, another possible scenario is: the user clicks the 'repairing line' button, the terminal display page displays the repairing line drawing area and the character information 'drawing the repairing line at the position', the user can draw lines along the longitudinal direction of the image, and the position of the repairing line drawn by the user is the adjusted position of the repairing line.
Optionally, in the foregoing embodiment, the step S102 of determining the area to be adjusted of the image based on the position information may include:
determining an initial area to be adjusted corresponding to the position information;
obtaining an eclosion value of an initial region to be adjusted;
and performing corresponding feathering treatment on the initial region to be adjusted based on the feathering value, and taking the feathering region obtained by the feathering treatment as the region to be adjusted of the image.
The corresponding relationship between the position information and the initial region to be adjusted is preset in the terminal device, and may be that one or more position information correspond to one initial region to be adjusted, and the server may determine the initial region to be adjusted corresponding to the position information of the adjusted repair line on the image based on the corresponding relationship.
In this embodiment, feathering is to make the edge of the area in the selected range achieve a hazy effect, the terminal device may use the initial area to be adjusted as the area in the selected range, the initial area to be adjusted has a default initial feathering value, the initial feathering value is adjustable, the terminal device determines a feathering value obtained by adjusting the initial feathering value, takes the feathering value as the feathering value of the initial area to be adjusted, performs feathering processing with the initial area to be adjusted as a center based on the feathering value to obtain a feathering area, and takes the feathering area as the area to be adjusted of the image.
In the present embodiment, the range of the feathering value may be 1 to 100, and the initial feathering value may be 50.
Further, in this embodiment, the obtaining of the feathering value of the initial region to be adjusted includes at least one of the following:
when the adjustment operation of the user for the initial feathering value of the initial region to be adjusted is detected, determining the adjusted feathering value based on the adjustment operation, and taking the adjusted feathering value as the feathering value of the initial region to be adjusted;
and determining a second image positioned in the initial region to be adjusted in the image, and determining a feathering value of the initial region to be adjusted based on the second image.
In the present embodiment, the feathering value of the initial region to be adjusted has the following two possible cases:
one possible scenario is: as mentioned above, the initial feathering value is preset in the terminal device, the user may adjust the initial feathering value, and when the terminal device detects an adjustment operation of the user for the initial feathering value, the adjusted feathering value may be determined based on the adjustment operation, so that the adjusted feathering value is used as the feathering value of the initial region to be adjusted. In this embodiment, the way for the user to adjust the initial feather value may be: the terminal display page is provided with an adjustment control with an eclosion value, the control can be an input box, a user can input a new eclosion value in the input box to adjust the initial eclosion value, the setting control can also be a sliding bar control, and the user can adjust the initial eclosion value through sliding.
Another possible scenario is: the terminal device may also automatically adjust or set a feathering value, and the terminal device may determine a second image located in the initial region to be adjusted in the image, and determine the feathering value of the initial region to be adjusted based on the content information of the second image, where determining the feathering value of the initial region to be adjusted based on the content information of the second image may be: if the initial feathering value is preset in the terminal device, the feathering value corresponding to the initial region to be adjusted can be obtained by adjusting the initial feathering value based on the content information of the second image.
The two possible scenarios described above may be applied in the following scenarios:
if the image (for example, the second image) corresponding to the initial region to be adjusted includes the content information of the thick line, the feathering value of the initial region to be adjusted may be adjusted (or set) to be larger, and if the image (for example, the second image) corresponding to the initial region to be adjusted includes the content information of the thin line, the feathering value of the initial region to be adjusted may be adjusted (or set) to be smaller.
For example, if the area of the feathering value is 1 to 100, and the second image corresponding to the initial region to be adjusted is a pillar, the feathering value of the initial region to be adjusted may be adjusted (or set) to 50 or more, and the second image corresponding to the initial region to be adjusted is a gate slit, the feathering value of the initial region to be adjusted may be adjusted (or set) to 50 or less.
Referring to fig. 6, a possible scenario of this embodiment is that a user clicks a "repair line" button, an initial repair line is displayed in a terminal display page, where the initial repair line includes a repair line in a lateral direction of an image and a repair line in a longitudinal manner of the image, and when a terminal device detects that the user pulls the repair line in the lateral direction to a certain position in the image rightwards, the repair line may be adjusted to the position, and meanwhile, an adjustment range of an eclosion value is 0 to 100, and the initial eclosion value is 50, an initial region to be adjusted may be determined based on the position of the repair line, and at this time, the eclosion value of the initial region to be adjusted is 50, and when the terminal device detects that the user adjusts the initial eclosion value, for example, the eclosion value is adjusted to 70, the terminal device adjusts the initial region to be adjusted based on the adjusted eclosion value, and obtains the region to be adjusted.
Optionally, the determining the reference line corresponding to the adjusted repair line in step S104 may include:
if the adjusted repairing line accords with the first preset direction, taking the reference line in the corresponding first preset direction as the reference line corresponding to the repairing line;
and if the adjusted repairing line accords with the second preset direction, taking the corresponding reference line in the second preset direction as the reference line corresponding to the repairing line.
If the adjusted repairing line is a line in a first preset direction of the picture, taking the line in the first preset direction of the terminal display page as a reference line corresponding to the repairing line, for example, if the first preset direction is a direction parallel to the length direction of the picture, taking a line parallel to the length direction of the terminal display page (which may be a transverse center line of the terminal display page) as the reference line;
if the adjusted repairing line is a line in a second preset direction of the picture, taking the line in the second preset direction of the terminal display page as a reference line corresponding to the repairing line, for example, if the second preset direction is a direction perpendicular to the length direction of the picture, taking a line (which may be a longitudinal center line of the terminal display page) perpendicular to the length direction of the terminal display page as the reference line;
optionally, before adjusting the first image located in the region to be adjusted of the image based on the reference line in step S105, the method may further include:
separating the background image of the image from other images except the background image of the image;
and determining a first image in the background image of the picture obtained by separation and positioned in the area to be adjusted.
The reason for the image damage may be image damage caused by the user using the cropping software, and one possible scenario is that, when the user uses the cropping software to adjust the image of the person in a certain image, the background image of the image is also adjusted accordingly, which results in image damage, so that after the general user adjusts the image of the person, the background image in the image needs to be adjusted, in this scenario, an image separation technique may be employed to separate the background image from other images (e.g., the image of the person) in the image, therefore, the terminal device can independently adjust the background image without affecting other images, and the terminal device can use the image corresponding to the area to be adjusted in the separated background image as the first image, so as to adjust the first image.
It can be seen that the present disclosure can adjust only the background image in the image without affecting other images (e.g., a person image, a product image) other than the background image.
Optionally, in the above embodiment, the adjusting the first image substantially adjusts an angle of the first image, or adjusts an angle of each line in the first image, in an implementation of the present disclosure, it is likely that the image is captured not horizontally but at a certain angle, so that there is a perspective angle in the captured image, and the perspective angle of the image can be understood as an angle of the image relative to a ground horizontal plane, and the perspective angle also needs to be considered when the image is adjusted.
One possibility is that, when adjusting the first image of the region to be adjusted, the first image is adjusted on the basis of the perspective angle, in particular:
optionally, the step S105 adjusts the first image located in the to-be-adjusted region of the image based on the reference line, and may include:
determining a perspective angle of the image;
the angle of the first image is adjusted based on the reference line and the perspective angle of the image.
After the terminal device determines the perspective angle of the image, the angle of the first image may be adjusted based on the angle of the first image relative to the reference line and the perspective angle of the first image, so that the adjusted first image also has the perspective angle relative to the ground horizon.
In this embodiment, the adjustment angle of the first image may be determined based on the reference line and the perspective angle, so as to adjust the angle of the first image, for example, if the reference line is parallel to the ground horizontal line, the inclination angle of the first image with respect to the ground horizontal line is X1 degrees, the perspective angle of the first image is X2 degrees, and the adjustment angle of the first image is X1+ X2 degrees; the first image may be adjusted to be parallel to the reference line based on the reference line, and then the perspective angle of the first image parallel to the reference line may be adjusted, for example, the image is photographed at an oblique X3 degree, the first image is adjusted to be parallel to the reference line, and then the first image is adjusted to be oblique X3 degree with respect to the ground horizontal line, and the value ranges of X1, X2, and X3 are all 0 to 180 degrees.
In the embodiment, the perspective angle of the image is considered when the first image is adjusted, so that the adjusted first image and the image to be adjusted are more coordinated, the visual effect of image display is increased, and the user experience is improved.
Another possible situation is that the image to be adjusted is already an image with the perspective angle adjusted in advance, specifically:
optionally, the acquiring of the image to be adjusted in step S101 may include:
acquiring an initial image and determining a perspective angle of the initial image;
and adjusting the perspective angle of the initial image to obtain an image to be adjusted.
The terminal equipment can acquire the initial image, determine the perspective angle of the initial image, adjust the angle of the initial image based on the perspective angle, and reduce the perspective angle to be close to or equal to 0 degree, so that the image to be adjusted obtained by adjusting the initial image is parallel to the horizontal line of the ground, and then, when adjusting the angle of the first image in the image to be adjusted, the first image is adjusted to be parallel to the reference line only by considering the angle of the first image relative to the reference line.
In this embodiment, when the terminal device adjusts the angle of the initial image, the initial image may or may not be clipped according to different types of the terminal device (or different sizes of screens of the terminal device), and the specific details are not limited herein.
In this embodiment, the perspective angle of the image may be adjusted in advance, so that the image is parallel to the ground horizontal plane, and when the image is restored, only the first image in the image needs to be adjusted based on the reference line, thereby simplifying the restoration process of the image, and the adjusted first image and the image to be adjusted are more coordinated.
The main application scenarios of the present disclosure are: when a user adjusts a character image by using image correcting software, the background image is often corrected and deformed, the method can be applied to the restoration of the background image in the image, when the user uses a liquefying function, lines of the background image need to be corrected after the details of characters in the image are adjusted, the user only needs to pull a restoring line to determine an area to be adjusted, at the moment, the character image and the background image can be separated by the terminal equipment, the character image is intelligently protected from being influenced, the method only plays a role in the background image, the deformed area is intelligently corrected, and the best effect is achieved by one key.
Referring to fig. 7, the present disclosure further provides an image processing apparatus, including:
an obtaining module 701, configured to obtain an image to be adjusted;
a first determining module 702, configured to, when an adjustment operation of a user on a repair line used for adjusting an image is detected, determine, based on the adjustment operation, position information of the adjusted repair line on the image;
