Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Fig. 3 is a flowchart of a method of an embodiment of a video shooting method according to an embodiment of the present invention. In this embodiment, the video shooting method may be applied to the mobile terminal shown in fig. 1 or fig. 2, and it is understood that the video shooting method may also be applied to electronic devices such as a tablet, an electronic book, and the like. The video shooting method comprises the following steps: S301-S305.

In step S301, a touch operation is acquired in a preview window, and a selected area is determined according to the touch operation;

in step S302, an initial video is captured;

in step S303, performing image recognition in each frame of image of the initial video according to the selected area;

in step S304, removing a target region in each frame of image according to the recognition result;

in step S305, each frame of image after the removal processing is displayed in a superimposed manner with a preset background image, so as to generate a processed video.

The present embodiment is described in further detail below:

specifically, in step S301, when the user has not started a shooting operation while shooting a video, the current preview interface is displayed in the preview window, and at this time, the touch operation of the user is received, and the selected area is determined according to the touch operation of the user. Wherein the selected region is to facilitate subsequent image recognition and processing.

In other embodiments, the step S301 may further include the following steps S3011 to S3013.

In step S3011, a slide gesture of the user in the preview window is acquired;

in step S3012, determining a trajectory range according to the slide gesture;

in step S3013, a selected area is determined from the trajectory range.

Specifically, in this embodiment, a sliding gesture of the user in the preview window is acquired. It can be understood that the embodiment is applied to a mobile terminal, which has a touch screen, and the touch screen can receive a click gesture and a sliding gesture. And when the user takes a sliding gesture in the preview window, determining the track range according to the sliding gesture. In this embodiment, when the trajectory range is a non-closed curve, the non-closed curve may be supplemented according to the initial position and the final position of the sliding gesture, so as to form a closed trajectory range. After determining the trajectory range, the selected area is further determined according to the trajectory range.

In this embodiment, the selected area may be determined in various ways, for example, the selected area may be determined according to the color within the track range, or may be determined according to whether there is a corresponding recognizable object within the track range. According to different determination modes, the mode in the image recognition process is different.

In one embodiment, the step S3013 may further include steps S30131-S30133.

In step S30131, the color of the pixel point in the trajectory range is counted;

in step S30132, determining a dominant color within the trajectory range according to the statistical result;

in step S30133, the main color is determined as a target color.

In this embodiment, after the track range is determined, the color corresponding to each pixel point in the track range is counted, and the dominant color is determined according to the statistical result, where the dominant color is the color with the highest color distribution ratio in the track range. The main color is used for subsequent image recognition and processing.

When color is used to determine the selected region, step S303 may further include the following steps S3031-S3033.

In step S3031, performing image recognition on each frame of image of the initial video;

in step S3032, at least one region in each frame of image, which is the same as the target color, is obtained;

in step S3033, when the area of the at least one region is greater than a preset threshold, it is determined that the at least one region is a target region.

Specifically, after the main color is determined to be the target color, each frame of image of the initial video is identified, and whether the target color exists in each frame of image is judged. In this embodiment, in each frame of image, there may be a plurality of regions corresponding to the target color, and at this time, further screening is performed according to the area size of the region, and when the area is larger than the preset threshold, the region is determined to be the target region. When the determination is performed according to the color, the pixel point of each frame of image may be analyzed, for example, by RGB, or by HSV, and the embodiment of the present invention is not limited thereto.

In another embodiment, the step S3013 may further include steps S30134-S30136 when the selected area is determined according to whether there is a corresponding recognizable object in the track range.

In step S30134, image recognition is performed on the trajectory range;

in step S30135, determining whether a preset object exists in the trajectory range according to the recognition result;

in step S30136, if the predetermined object exists, the area to which the predetermined object belongs is determined to be the selected area.

In this embodiment, after the track range is acquired, image recognition is performed on the track range, and whether a preset object exists in the track range is determined. The preset object may be a human body, an object, or the like, and may be preset by a user. For example, a user defines a certain range through a sliding gesture on a preview interface, and then selects and identifies a human body in the certain range, at this time, after the track range corresponding to the sliding gesture is obtained, image identification is performed on the track range, whether the human body exists is judged, and if the human body exists, the area corresponding to the human body is determined as the selected area. In other embodiments, an existing image recognition algorithm, such as a deep learning algorithm, may be invoked when performing image recognition, so as to more quickly recognize a relevant target object in an image.

When the selected region is determined using the preset object, further, step S303 may further include the following steps S3034 to S3036.

In step S3034, performing image recognition on each frame of image of the initial video;

in step S3035, determining whether a target object identical to the selected region exists in each frame of image;

in step S3036, if the target object exists, the target object corresponding region is determined as the target region.

Specifically, when the preset object is used for determination, image recognition is performed on each frame of image of the initial video, and whether a corresponding object exists in each frame of image is determined. For example, if the preset object determined by the user through the track range is a vase, whether the vase exists or not is identified in each frame image, and if the preset object exists, the area corresponding to the vase is determined as the target area.

After the target area is obtained, in step S304, the corresponding processing is performed on the target area existing in each frame of image, in this embodiment, the corresponding target area is removed according to the recognition result. Specifically, the pixel point information corresponding to the target area is deleted, and the target area is hollowed out, so that the target area and the subsequent image can be conveniently displayed in a superposed manner. By the method, the corresponding image information can be deleted in a targeted manner, deletion is performed according to user selection, each frame in the video is automatically processed, and the method is more efficient and concise.

In step S305, in order to generate a corresponding special effect video, after the target area is deleted, each frame image after the processing needs to be superimposed on the background image. In one embodiment, the background image is obtained by initial video acquisition, that is, by parsing the initial video, a frame of image without occlusion is acquired as the background image. In other embodiments, the background image may also be obtained by reminding a user to take a picture before the video is taken, and the embodiments of the present invention are not limited thereto.

In one embodiment, the step S305 may further include the following steps S3051-S3052.

In step S3051, obtaining a preset background image according to the initial video;

in step S3052, each frame of image after the removing process is superimposed with the background image, where the background image is located at a lower layer of the layer, and each frame of image is located at an upper layer of the layer.

Specifically, the background image is arranged on the lower layer, and each processed frame image is arranged on the upper layer, so that the background image can be seen in the hollow area, and the stealth special effect is realized. By the method, when the user shoots the video, the corresponding area is selected in the preview area, and the area with the same color or object selected by the user can be automatically processed by identifying the area, so that the transparent special effect is realized, and the interest of video shooting is improved.

According to the video shooting method in the embodiment of the invention, the area selected by the user is obtained, the shot initial video is processed according to the selected area, the specific area is removed from each frame of image, and the specific area is overlapped with the background image, so that the special effect of stealth is realized, the interest of the video is improved, the shooting by the user is facilitated, and the user experience is improved.
