Problems solved by technology
However, at present, the above-mentioned image segmentation process is usually carried out manually. Artists need to perform artificial image segmentation and image processing on each video frame according to the requirements. Faced with a video with a large number of frames, the process of manual image segmentation is undoubtedly time-consuming. quite strenuous
[0003] So in order to solve this problem, for example, when shooting a movie, artificially arrange an easy-to-handle background, such as shooting a movie scene with a green curtain as the background, and then use special video processing software to replace the green background with the required background. The processing method also has considerable limitations. If the foreground structure is complex, such as when there is a large area of hair in the foreground, the processing speed of this foreground and background segmentation method is very slow, and it cannot achieve real-time segmentation of hair

The present invention discloses a real-time hair segmentation method and system, wherein the method includes: acquiring the current video frame image; separating the current video frame image into three channel images in RGB color mode; dividing the previous video frame of the current frame The first hair segmentation mask associated with the image and the three channel images associated with the current video frame image are input into a pre-trained hair segmentation model, and the current video frame image is output through model prediction. The associated second hair segmentation mask; repeat the above steps to complete the real-time hair segmentation of all video frame images. In the present invention, the three-channel image of one frame of original image and the hair segmentation mask model corresponding to the original image are input, and the hair segmentation mask of the current frame is predicted and output, which greatly improves the speed of hair segmentation and ensures the real-time performance of hair segmentation.
Description
technical field [0001] The invention relates to the technical field of image segmentation, in particular to a real-time hair segmentation method and system. Background technique [0002] Image segmentation is a widely used technique that enables film directors and video content creators to separate the foreground of an image from its background and treat them as two distinct visual layers. By modifying the layer (such as recoloring, masking or replacing, etc.), the image scene that is originally boring or does not meet the visual requirements becomes more eye-catching and improves the visual effect. However, at present, the above-mentioned image segmentation process is usually carried out manually. Artists need to perform artificial image segmentation and image processing on each video frame according to the requirements. Faced with a video with a large number of frames, the process of manual image segmentation is undoubtedly time-consuming. Quite laborious. [0003] So in...
