Referring to fig. 1, fig. 1 is a flowchart of a picture cropping method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
in the embodiment of the present invention, the picture to be cut may be one or more pictures, for example, an operation interface may be provided for a user to input the picture to be cut, the user generally refers to an advertisement publisher, and the picture to be cut may be a picture that is processed by the user in advance, for example, a picture that is formed after a photographed picture is processed, or a picture that is formed after a network picture or a screenshot is processed.
102, performing image cropping processing on the image to be cropped according to a target image cropping pickup engine to obtain a target image; the target clipping and drawing picking engine is a clipping and drawing picking engine constructed based on target clipping and drawing factors, and the target clipping and drawing factors are generated iteratively according to clipping and drawing behaviors.
In an optional embodiment, the user may select a picture cropping mode, for example, a picture to be cropped may be cropped in a manual picture cropping mode, or a picture to be cropped may be automatically cropped in an automatic picture cropping mode. Specifically, in the automatic image cropping mode, the target image cropping engine may be adopted to perform image cropping processing on an image to be cropped, so as to obtain a target image.
The target picture may have a variety of styles, for example, in this embodiment, the target picture may have a style of PC, wise, bar, clue, or the like.
Specifically, the target picture may include a picture of one style, or may include pictures of multiple styles, which is not further limited herein.
The target clipping and drawing picking engine can comprise one or more clipping and drawing picking sub-engines corresponding to one style, wherein a certain clipping and drawing picking sub-engine A can be a clipping and drawing picking engine constructed based on the clipping and drawing factor A; the pattern cutting factor A is obtained by carrying out iterative processing on pattern cutting behaviors corresponding to pictures of a pattern A obtained by cutting the pictures by a plurality of users, and the pattern A corresponds to the pattern cutting and picking sub-engine A.
For example, the user a cuts the picture 1 by the picture cutting behavior 1 to obtain a picture in the style 1, and cuts the picture 1 by the picture cutting behavior 2 to obtain a picture in the style 2; the user B cuts the picture 2 to obtain a picture with a style 1 through the picture cutting behavior 3, and cuts the picture 3 to obtain a picture with a style 2 through the picture cutting behavior 4; the user C crops the picture 4 by cropping behavior 5 to obtain a picture of style 1, and crops the picture 4 by cropping behavior 6 to obtain a picture of style 2.
In this way, by performing iterative processing on the referring diagram behaviors 1, 3 and 5, a referring diagram factor can be obtained, and based on the referring diagram factor, the referring diagram picking sub-engine 1 corresponding to the style 1 can be constructed. Similarly, by performing iterative processing on the chart clipping behaviors 2, 4 and 6, a chart clipping factor can be obtained, and the chart clipping sub-engine 2 corresponding to the style 2 can be constructed based on the chart clipping factor.
The picture to be cut is cut by the picture cutting and picking sub-engine 1 to obtain a picture with a style 1; the picture of the style 2 can be obtained after the picture to be cropped is cropped by the image cropping and picking sub-engine 2.
The embodiment of the invention carries out image cropping processing on the image to be cropped by the target image cropping engine constructed based on the image cropping behavior of the user, thereby realizing automatic image cropping on the image. Therefore, the image cutting is not needed manually, and the advertisement promotion efficiency can be improved.
Further, referring to fig. 2, based on the foregoing embodiment, in this embodiment, the foregoing step 102 includes:
the first chart cutting and picking engine is used for carrying out iteration generation on chart cutting factors corresponding to the first chart cutting and picking engine according to the chart cutting behaviors of different users; and iteratively generating a graph cutting factor corresponding to the second graph cutting and picking engine according to the graph cutting behavior of the user.
It should be noted that the configuration of the first chart picking engine may be set according to actual needs, for example, in this embodiment, the configuration of the first chart picking engine and the second chart picking engine is described in detail.
Specifically, referring to fig. 3, in an optional embodiment, before receiving the user input of the to-be-cut picture, the method further includes:
103, acquiring first history graph clipping behaviors of different users on each pattern of picture;
105, constructing a clipping and picking sub-engine corresponding to each style according to the clipping factor corresponding to each style;
Wherein the first chart picking engine comprises a chart picking sub-engine corresponding to each style.
In this embodiment, the chart clipping and picking sub-engine corresponding to each style may be constructed according to the first history chart clipping behavior corresponding to each style, and the chart clipping and picking sub-engine may include one or more chart clipping and picking sub-engines corresponding to various styles. When the first image cropping engine is used for cropping images to be cropped, images in one or more types can be obtained, and specifically, when the first image cropping engine comprises a plurality of image cropping sub-engines, the obtained target images comprise images in the types corresponding to the plurality of image cropping sub-engines. Since a plurality of styles of cropped pictures can be obtained at one time, the cropping operation is simplified. Specifically, the first history cropping behavior is a cropping behavior generated by manually cropping each style of picture by a plurality of different users. The cropping behavior may include an area or location of cropping the picture.
In another alternative embodiment, referring to fig. 4, before receiving the user input of the to-be-cut picture, the method further includes:
the second chart picking engine comprises at least one chart picking sub-engine corresponding to the style.
In this embodiment, when the user selects the image cropping mode, if the user selects the manual image cropping mode, the image to be cropped may be displayed on the image cropping interface, and an image cropping toolbar may be displayed. The user can manually cut the picture to be cut by using the picture cutting tool. At this time, the current image cutting behavior of the user is recorded and stored. Specifically, when the number of pictures in a certain style obtained by manual cropping by a user is greater than a preset value, iteration can be performed on cropping corresponding to the style to obtain a cropping factor corresponding to the style, and then the cropping picture pickup sub-engine corresponding to the style is constructed based on the cropping factor. Since the second chart cropping engine is constructed based on the manual cropping behavior of the user in the embodiment, the pertinence of the chart cropping can be improved, and the satisfaction of automatic chart cropping can be improved. It should be understood that the sequence of constructing the first and second referring engines is not particularly limited, that is, the steps 103 to 105 may be performed before the steps 106 to 108 are performed, or may be performed after the steps 106 to 108 are performed, and no further limitation is made herein.
Further, if the system includes a first chart pickup engine and a second chart pickup engine, the selection manner of the chart pickup engine may be set according to actual needs, for example, in this embodiment, specifically, the step 1021 includes:
step 10211, receiving a cutting instruction input by the user;
step 10212, if the cropping instruction does not include the second target style selected by the user, or the cropping instruction includes the second target style, and the second cropping engine does not include the cropping sub-engine corresponding to the second target style, performing cropping processing on the picture to be cropped according to the first cropping engine to obtain a first target picture;
step 10213, if the cropping command includes the second target pattern and the second cropping pattern pickup engine includes the cropping pattern pickup sub-engine corresponding to the second target pattern, performing cropping processing on the to-be-cropped picture according to the cropping pattern pickup sub-engine corresponding to the second target pattern to obtain a second target picture.
In the present embodiment, a target chart pickup engine for performing chart clipping can be determined by judging whether the user selects a picture of a specific style. When the style of the clipped image is selected by the user, whether the second clipped image picking engine comprises a clipped image picking sub-engine corresponding to the style or not can be judged, and when the clipped image picking sub-engine exists, clipping is carried out according to the clipped image picking sub-engine; when the cutting picture picking sub-engine does not exist, cutting pictures to be cut according to the first cutting picture picking engine. In addition, when the style of the trimming picture is not selected by the user, the trimming picture can be trimmed according to the first trimming picture pick-up engine.
It should be noted that, in another alternative embodiment, the corresponding clipping pattern type option may be provided according to the corresponding pattern of the clipping pattern picking sub-engine included in the second clipping pattern picking engine. At the moment, when the user selects a chart cutting style, cutting the chart according to the second chart cutting pick-up engine; when the user does not select the cropping pattern, the cropping pattern is carried out according to the first cropping pattern picking engine.
It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
