Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings according to embodiments.
Generally, in an image, a plurality of image content objects exist, each image content object corresponds to a content, and specifically, may be an entity, a scene, and the like, such as a tree, a vehicle, and the like, and further, a scene describing sunset.
The invention designs an image content label control, which comprises a text box for displaying the name of an image content object and a closed area for marking the coverage area of the image content object, wherein the image content label control and the image content object are in one-to-one correspondence, and the image content label control is used for one-to-one management of the image content object, so that the image content label control is used for realizing the management of the image content label of the image.
Referring to fig. 1, fig. 1 is a flowchart of a method for managing image content tags according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
The image content label corresponding to the image is composed of the content labels of all image content objects in the image.
In order to reduce the workload of the user in managing the image content tags, in the embodiment, the content tags of each image content object are automatically added to the image by using the existing image recognition technology. This process may occur before the image is captured and written to the file, or may be manually triggered by the user as desired after the capture is complete.
In the prior art, the image recognition technology can not only recognize an object (image content object) in an image, but also obtain the position and size of the corresponding object in the image, and therefore, in this embodiment, the designed image content tag includes three contents:
a) an image content object name for a keyword that characterizes a specific content (meaning) of the image content object;
b) image content object position: for representing the position of the image content object in the picture, in this embodiment, the center coordinates of the image content object may be used for representation;
c) image content object size: the coverage area for representing the image content object is represented by a closed area, and specifically, the size parameter of the closed area may be used for representing the coverage area of the image content object, for example, a rectangular closed area capable of covering the image content is used for representing the coverage area of the image content object, so that the size of the image content object may be represented by a length and a width, and the position of the image content object may be represented by a center coordinate of the rectangle. In this way, the position and size of the image content object in the image can be clearly indicated according to the position and size of the image content object.
In this embodiment, the identified and generated image content tag is written as image metadata in an image file, and supports all formats of image files. Therefore, the image file can be maintained and not lost in the processes of network sharing, device-to-device transmission and the like of the image file. The user can read the image content label at any time to modify, add or delete.
And 102, managing the image content labels of the images by using the image content label control according to the principle that the image content label control corresponds to the image content objects one to one.
In this embodiment, each image content object corresponds to one image content label control, and the image content label control is used to manage the content label of the image content object.
The content tag control of the image content object includes: a text box for displaying the name of the image content object and a closed area for indicating the coverage of the image content object. Wherein the content of the first and second substances,
the text box in the image content label control is associated with the image content object name in the content label of the image content object, if a user inputs a character string in the text box and submits the character string, the character string is stored as the image content object name in the content label of the image content object; when the user inquires the content tag of the image content object, the image content object name is read from the content tag of the image content object and displayed in the text box.
The closed region in the image content label control is associated with the image content object position and the image content object size in the content label of the image content object, that is, the center position of the closed region in the image content label control is (or determines) the image content object position in the content label of the image content object, and the size parameter of the closed region in the image content label control is (or determines) the image content object size in the content label of the image content object.
In this embodiment, the image content label control is suspended above the image content object as shown in fig. 2, that is, the image content label control corresponding to the image content object, where a text box with a "car" character is a text box of the image content label control; a rectangular area defined by a dotted line is a closed area of the image content label control; "position" means the image content object position, which is the center of the rectangular area; the name refers to the name of the image content object and is the character content in the text box; "size" means the size of the image content object, expressed in terms of the length and width of the rectangular area.
In practical applications, the management of the content of the image tag mainly includes three operations of editing (modifying), adding (creating), and deleting the content tag of any image content object, which are described below:
editing (modifying) image content label
When editing the content tag of the image content object, the user can edit not only the image content object name in the content tag of the image content object but also the image content object size and the image content object position in the content tag of the image content object.
The user can click the text box in the image content label control suspended above the image content object, the original content in the text box is removed, the input keyboard pops up, the user can input a new image content object name, then the user can press a enter or submit button, so as to trigger a first content label editing command (carrying the new image content object name), and the background can replace the image content object name in the content label of the image content object with the new image content object name according to the first content label editing command and update the corresponding content in the image file (namely, update the image content object name in the content label of the image content object stored in the image file). The process of editing the image content object name in the content tag of the image content object by entering a new image content object name in the textbox in the image content tag control is illustrated in fig. 3 a: firstly clicking a text box in the image content label space to enter an editing state, and then inputting a character string in the text box in the editing state.
A user may click on a closed area of an image content label control, the closed area may become an editable mode, the user may change the size and position of the closed area by dragging the closed area, for example, a rectangle is used as the closed area, the size and position of the closed area may be changed by dragging two points on a diagonal of a rectangular frame, and then a enter or submit button may be pressed, thereby triggering a second content label editing command (carrying a center coordinate and a size parameter of an adjusted image), the background may replace an image content object position and an image content object size in a content label of an image content object corresponding to the image content label control with the center coordinate of the closed area after the adjustment and the size parameter of the closed area after the adjustment, respectively, and update corresponding content in the image file (that is, update the image content object position and image content object size in the content tag of the image content object in the image file). The process of editing the image content object position and image content object size in the content label of the image content object by adjusting the closed area position and size in the image content label control is shown in fig. 3 b: and firstly, selecting a closed area of an image content label space, and then adjusting the position and the size of the closed area.
It should be noted that the text box and the closed area of the image content label control are integrated, and when the center position of the closed area of the image content label control is changed, the position of the text box in the image content label control is adjusted accordingly.
As can be seen from the above, in this embodiment, according to the principle that the image content label control corresponds to the image content object one to one, the method for managing an image using the image content label control specifically includes:
when a first content label editing command triggered by a user inputting a character string in a text box in an image content label control corresponding to any image content object is received, replacing the image content object name in the content label of the image content object with the character string, and updating an image file according to the character string;
when a second content label editing command triggered by the fact that a user adjusts the size of a closed area in an image content label control corresponding to any image content object is received, the position of the image content object and the size of the image content object in a content label of the image content object are replaced by the center coordinate of the closed area after the size is adjusted and the size parameter of the closed area after the size is adjusted respectively, and the image file is updated accordingly.
Second, add (newly create) image content label
When a certain image content object does not have a corresponding image content label control, a user can select to newly create an image content label control for the certain image content object.
An image content label adding control button (for example, a plus button at the upper right corner of fig. 4 a) can be clicked to trigger a new image content label control command, and a background newly creates an image content label control according to the new image content label control command, at this time, the sizes of the content in the text box and the closed area in the new image content label control are default, and the default text box content, the center coordinate of the closed area, and the size parameter can be written into an image file as the image content object name, the image content object position, and the image content object size in the content label of the corresponding image content object, respectively. The user may then write the exact image content object name, image content object location position, and image content object size to the image file in the manner that the image content tag was edited. In particular, the amount of the solvent to be used,
the user inputs the image content object name corresponding to the image content object in the text box in the image content label control, then the user can press the enter or submit button, so as to trigger the first content label editing command, the background replaces the image content object name in the content label of the image content object with the character string input in the text box according to the first content label editing command, and updates the corresponding content in the image file.
And the background replaces the position of the image content object and the size of the image content object in the content label of the image content object with the central coordinate of the closed area after the position and the size are adjusted and the size parameter of the closed area after the position and the size are adjusted respectively according to the second content label editing command, and updates corresponding content in the image file.
By newly creating an image content label control, modifying the content of a text box in the image content label control and adjusting the position and the size of a closed area in the image content label control, the operation of adding a content label of an image content object to the image content label is realized, and the specific operation process is shown in fig. 4 a. It should be noted that, the operation process of modifying the content of the text box in the image content label control and the operation process of adjusting the position and size of the closed region in the image content label control are not in sequence.
In practical implementation, in the process of triggering a command of creating an image content label control by a user, the target position of the image content label control can be specified, for example, the user may select the image content tag control by clicking on an add image content tag control button (e.g., the "+" button in the upper right corner of FIG. 4 b), and using an operator to specify a target position (which may be a range of areas or a point) for the image content tag control on the display screen of the device, for example by indicating the position and size of the image content tag space (and at the same time the position and size of the image content object) on the display of the device in a sliding manner with an operator, thereby triggering a new image content label control command carrying the target position, therefore, the background newly builds an image content label control at the target position specified by the command of the newly-built image content label control. Then, the operation of adding the content tag of the image content object to the image content tag can be realized by modifying the content of the text box in the image content tag control and adjusting the position and the size of the closed area in the image content tag control, and the specific operation process is shown in fig. 4 b.
As can be seen from the above, in this embodiment, according to the principle that the image content label control corresponds to the image content object one to one, the method for managing an image using the image content label control specifically includes:
when a newly-built image content label control command triggered by a user is received, an image content label control is newly built, a content label of an image content object corresponding to the newly-built image content label control is generated according to a default character string in a text box in the newly-built image content label control, the center coordinate and the size parameter of a closed area in the newly-built image content label control, and the content label is written into an image file as image metadata;
if a first content label editing command of an image triggered by a character string input by a user in a text box in the newly-built image content label control is received, replacing the image content object name in the content label of the image content object corresponding to the newly-built image content label control with the character string, and updating the image file according to the character string;
and if a second content label editing command which is triggered by the fact that a user drags the newly-built image content label control to a specific image and the size of a closed area in the newly-built image content label control is adjusted is received, replacing the image content object position and the image content object size of a content label of an image content object corresponding to the newly-built image content label control with the center coordinate of the closed area after the size is adjusted and the size parameter of the closed area after the size is adjusted respectively, and updating the image file accordingly.
During a new image content label control command triggered by a user, the target position of the image content label control can be specified; the target position is also carried in the new image content object label control command; therefore, an image content label control can be newly built at the target position specified by the new image content object label control command.
Thirdly, deleting image content label
Sometimes, for example, when an object is not a salient object in the image, it is not necessary to generate a content tag for the image content object and to generate an image content tag control corresponding to the object, and then the user may select to delete the content tag of the image content object and the corresponding image content tag control.
The user can click any area in the image content object coverage range defined by the closed area in the image content label control to select the image content object, then click a delete image content label control button (such as a "-" button in the upper right corner of fig. 5) to trigger a delete image content label control command, the background deletes the selected image content label control according to the delete image content label control command, and simultaneously, deletes the content label of the image content object in the image file. The deletion process of the image content tag is specifically shown in fig. 5.
As can be seen from the above, according to the principle that the image content label control corresponds to the image content object one to one, managing the image by using the image content label control further includes: when an image content label deleting control command triggered after a user selects a certain image content object is received, deleting the image content label control corresponding to the image content object, and deleting the content label of the image content object in the image file.
