Title:
IMAGE CODING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/022467
Kind Code:
A1
Abstract:
An image coding method and apparatus, and an electronic device. The image coding method comprises: determining a reference pixel set of the current processing block for image division, wherein the reference pixel set is used for intraframe prediction of the current processing block; successively filtering each reference pixel in the reference pixel set, wherein one filtered reference pixel in the reference pixel set is taken as the input for a filter for filtering an adjacent reference pixel to be filtered to the filtered reference pixel at the next position; calculating, according to the filtered reference pixel set, a prediction block for the current processing block; and performing coding according to the prediction block and the current processing block.
