Title:
METHOD FOR MOTION ESTIMATION, NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/197229
Kind Code:
A1
Abstract:
A method for motion estimation, a non-transitory computer-readable storage medium, and an electronic device are provided. The method includes the following. An error between a block to be matched and each of reference blocks is determined to obtain multiple errors. At least one candidate block is determined from the reference blocks according to the multiple errors. A random number range is determined according to a displacement between the block to be matched and each of the reference blocks. Random motion vectors are obtained by using a motion vector between the block to be matched and each of the at least one candidate block as a basic motion vector and random numbers within the random number range as increments. A target motion vector corresponding to the block to be matched is determined according to the random motion vectors.
