Abstract

The invention provides a motion estimation method, a motion estimation device, a computer readable storage medium and electronic equipment, and relates to the technical field of image and video processing. The motion estimation method comprises the following steps: determining an error between a to-be-matched block and a candidate block, the to-be-matched block being an image block in a current frame image, and the candidate block being an image block in a reference frame image; selecting at least two candidate blocks with the smallest error with the to-be-matched block from the candidate blocks; determining a search range in the reference frame image according to the positions of the at least two candidate blocks; and searching a global optimal block of the to-be-matched block in the search range, and obtaining an optimal motion vector of the to-be-matched block through the global optimal block. According to the invention, motion estimation can be carried out in different scenes, andthe accuracy and efficiency are high.

Description

technical field [0001] The present disclosure relates to the technical field of image and video processing, and in particular to a motion estimation method, a motion estimation device, a computer-readable storage medium, and electronic equipment. Background technique [0002] Motion Estimation refers to the calculation of the relative offset of the target between consecutive frames of images in the video to obtain the motion vector of the target. It is widely used in video coding, motion compensation, video frame interpolation and other fields. [0003] In the prior art, in order to achieve motion estimation, each frame of the image sequence is usually divided into many non-overlapping blocks, and the displacement of all pixels in the block is considered to be the same, and then traversed within a given range of the reference frame , to find the similar blocks of the current block, so as to obtain the motion vector between the current block and the similar blocks. However, ...
