Method for identifying motion foreground in video and method for determining target position in video

A target location and video technology, which is applied to electronic devices capable of tracking targets in videos, tracking targets in videos, tracking storage devices for targets in videos, implementing video implantation in storage devices for target occlusion, and determining target positions in videos. Realize video implant target occlusion, identify the moving foreground area in the video, and can solve the problems that the image of the embedded object cannot be occluded, the image of the embedded object cannot be blended with the scene, and high cost

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

Embodiment Construction

[0216] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0217] An embodiment of a method for identifying a moving foreground in a video of the present application takes the processing of a video frame to be processed during video implantation as an example, and its flow chart is as follows figure 1 shown, including the following operations:

[0218] Step 101, acquire video frames to be processed that include a video implant target area.

[0219] For the case of implanting the image of the object into the video, the implanted object is in the scene embodied in the video, and whe...

Abstract

The invention discloses a method for identifying a motion foreground in a video. The method comprises the steps of: acquiring a to-be-processed video frame containing a video implantation target region; determining a corresponding region of interest according to the video implantation target region; for the region of interest, performing rough segmentation on a motion foreground of the region of interest through comparing the foreground and a background; and for a rough segmentation result, performing fine segmentation on the motion foreground of the region of interest through image edge processing, so as to obtain a motion foreground segmentation result. The method can achieve the effect of identifying the motion foreground in the video frame quickly and precisely in real time.
