Abstract

The invention relates to a motion vector post-processing method comprising the steps that a local area corresponding to a current processing block is acquired, and the current processing block is acquired according to motion estimation of a to-be-processed image frame; motion vector distribution corresponding to the local area of each current processing block is acquired, and the motion vector state of the current processing block is determined based on the distribution state of the motion vector of the current processing block in the motion vector distribution; when determining that the motion vector state is an abnormal state, a candidate motion vector of the current processing block is obtained; and the motion vector of the current processing block is corrected according to the candidate motion vector to obtain a target motion vector of the current processing block. The invention further discloses a motion vector post-processing device, electronic equipment and a computer readable storage medium. The image quality can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a motion vector post-processing method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of computer technology, image processing technology has become more and more diversified. Motion estimation compensation for images is a video coding and video processing, such as in the frame interpolation method based on MEMC (Motion Estimate and Motion Compensation, motion estimation motion compensation) A widely used technique. [0003] There may be wrong motion vectors in the motion vectors obtained by motion estimation. The traditional post-processing method of motion vectors has the problem of inaccurate detection of wrong motion vectors. The target image obtained by the existing technology has the problem of low image quality. Contents of the invention [0004] Embodiments ...
