PIXEL PREDICTION METHOD AND DEVICE

摘要

An embodiment of the present invention provides a pixel prediction method, including: obtaining an average pixel value of reference pixel points on a long side of a current block if the current block is rectangular and coded or decoded adjacent blocks of the current block are all available, where the reference pixel points are all located at boundaries of the adjacent blocks near the current block; and obtaining a prediction pixel value of the current block according to the average pixel value of the reference pixel points on the long side. According to the pixel prediction method and apparatus provided in the embodiments of the present invention, a prediction pixel is obtained from corresponding adjacent blocks according to a shape of the current block, meeting a pixel distribution rule.
