Abstract

A method and device for generating a predicted value of an image that are mostly used to generate a predicted value of a current block during image encoding or decoding. The method includes: determining a searching scope, wherein multiple motion vectors are included in the searching scope; performing up-sampling interpolations on first reference blocks, corresponding to the motion vector in the searching scope, in a reference image of the current block by using a first filter to obtain up-sampled first reference blocks; by using the up-sampled first reference blocks, obtaining at least one candidate motion vector corresponding to the current block; performing up-sampling interpolations on second reference blocks, corresponding to the at least one candidate motion vector, in the reference image of the current block by using a second filter to obtain up-sampled second reference blocks; combining the up-sampled second reference blocks to obtain a predicted value of the current block.

Description

technical field [0001] The invention relates to image codec technology in the field of signal processing, in particular to a method and device for generating image prediction values. Background technique [0002] With the continuous development of video coding technology, inter-frame motion search and compensation technology can effectively remove the time redundancy of video content, and the coding efficiency has been greatly improved; motion information is obtained through motion estimation and transmitted to the decoding end, The video image is predicted and reconstructed by the decoding end through the method of motion compensation. The inter-frame motion compensation prediction technology refers to: during the encoding and decoding process, the motion vector obtained by searching is used to perform motion compensation, so as to realize the corresponding encoding and decoding operations. [0003] As a codec method, the derivable motion vector technology at the decoding ...
