Abstract

The invention discloses an intra-frame prediction method, device, coder and storage device. The intra-frame method includes: obtaining reference pixels of the current coding block, the width and height of the current coding block are not equal; using the size information of the current coding block and the current prediction mode to select the filtering mode of the current coding block, the size information of the current coding block includes The width and / or height of the current coding block; using the reference pixels processed according to the filtering mode to obtain the predicted value of each pixel in the current coding block under the current prediction mode. Through the above method, the present invention can improve the reference pixel filtering effect of the non-square current coding block.

Description

technical field [0001] The present application relates to the field of video coding, in particular to an intra prediction method, an encoder and a storage device. Background technique [0002] Because the amount of video image data is relatively large, it usually needs to be encoded and compressed before being transmitted or stored. The encoded data is called a video stream. Limited by hardware and other conditions, such as limited storage space, limited transmission bandwidth, etc., the encoder always hopes to make the video stream as small as possible. [0003] Video coding mainly includes video acquisition, prediction, transform quantization and entropy coding. The prediction is divided into two parts: intra prediction and inter prediction, which are used to remove spatial redundancy and temporal redundancy respectively. [0004] At present, intra prediction mainly includes four processes of reference pixel acquisition, reference pixel filtering, prediction value acquisi...
