Problems solved by technology

However, when the camera moves or there are a large number of moving objects in the video, the images of the embedded objects often cannot be perfectly integrated with the scene. When the image of the embedded object cannot show the effect of being occluded, etc.
[0005] In order to achieve the effect of seamless embedding, traditional video embedding methods often require professionals to manually process each embedding in the later stage, which results in relatively high costs and makes it less practical

Abstract

The present application discloses a method for identifying a moving foreground in a video, comprising: acquiring a video frame to be processed that includes a video implant target area; determining a corresponding region of interest according to the video implant target area; For the region of interest, the moving foreground of the region of interest is roughly segmented by comparing the foreground with the background; for the rough segmentation result, the moving foreground of the region of interest is finely segmented through image edge processing to obtain the moving foreground segmentation result. It can quickly and accurately identify the moving foreground in the video frame in real time.
