Problems solved by technology

However, the video screen corresponding to the video stream generated by the live broadcast inevitably has a large number of violently moving small object images. After the live video stream is denoised using the existing video stream noise reduction method, the video screen corresponding to the video stream will appear blurred. The problem

Abstract

The invention relates to a video stream noise reduction method and device, an electronic device and a storage medium. The method includes the steps: receiving a video stream, wherein the video streamincludes a plurality of image frames; determining a current to-be-denoised reference image frame of the current video stream; searching for all candidate image frames of the reference image frame fromthe video stream; dividing the reference image frame into a plurality of image blocks; respectively merging and splicing each of the image blocks with similar image blocks in each of the candidate image frames to obtain a target image frame after noise reduction processing. The method provided by the present invention can achieve the effective noise reduction of the video stream, and enables thevideo stream to display a clear video image.

Description

technical field [0001] The present disclosure relates to the technical field of video processing, and in particular, to a video stream noise reduction method and device, electronic equipment, and a storage medium. Background technique [0002] Currently, as the functions of electronic devices become more and more powerful, various types of applications emerge as the times require, such as: social networking applications, live broadcast applications, and payment applications. Users can live broadcast or watch live broadcasts through live broadcast applications installed on electronic devices. [0003] Video streams are generated during live broadcasting. Currently, when noise reduction is performed on video streams, only the independent image frames in the video stream are denoised. This method of denoising video streams is suitable for videos with static images. . However, the video screen corresponding to the video stream generated by the live broadcast inevitably has a l...
