Abstract

The invention relates to the technical field of video processing, in particular to a video processing method, a system, device and a medium. The method aims at solving the problems that an existing matting method is large in limitation and small in extraction range. In order to achieve the purpose, the video processing method comprises the steps of acquiring a target background image, image frames in a video and a depth distribution map corresponding to the image frames; segmenting the image frame to obtain an image segmentation result; performing thresholding operation on the depth distribution map to obtain a distribution map thresholding result; determining a foreground and background distribution map based on an image segmentation result and a distribution map thresholding result; performing synthesis based on the image frame, the target background image and the foreground and background distribution image to obtain a final image; and outputting the final image. According to the method, the requirement of real-time image matting under the condition of no green screen is met, foreground and background segmentation is carried out by introducing the depth distribution map, the complex foreground and background judgment problem is avoided, and accurate extraction of non-portrait objects in the image frames is achieved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video processing method, system, device and medium. Background technique [0002] With the development of video processing technology, webcast events are becoming more and more popular. In the live broadcast scene, due to privacy considerations, the video anchor often hopes to replace the real background picture behind him in the screen with a virtual background to obtain a better live broadcast effect. [0003] However, most of the current video keying algorithms are based on green screen implementation. This method is mostly used in the film and television industry, and the keying accuracy is better. However, this requires the anchor to use a pure green screen to build a solid color background during the live broadcast, which is harmful to the live broadcast environment. Larger restrictions. [0004] There are also non-green screen matting tools in the prio...
