IMAGE PREDICTION PROCESSING METHOD AND RELATED DEVICE

摘要

An image prediction method and related device, the image prediction method comprising: obtaining a wedge-shape query template set of an image block having a size of N * M; downsampling K binary partition templates to obtain K binary partition templates processed by downsampling, wherein the K binary partition templates are in the wedge-shape query template set of the image block having the size of N * M, and K is an integer greater than zero; adding the obtained K binary partition templates processed by downsampling to a wedge-shape query template set of an image block having a size of P * Q, and performing prediction on the image block having the size of P * Q by utilizing the wedge-shape query template set of the image block having the size of P * Q; N and the M are positive integers, N/P is a positive integer multiple of 2, and M/Q is a positive integer multiple of 2. The solution provided in an embodiment of the present invention facilitates reducing a storage space of a codec device required for storing a wedge-shape query template set.
