Embodiment Construction

[0090] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without any creative effort fall within the protection scope of the present invention.

[0091] In video codec standards, such as Moving Picture Experts Group (MPEG) and Advanced Video Coding (H.264 / AVC), an image block, or macro block, It is called a coding unit (Coding Unit) in the High Efficiency Video Coding (HEVC) standard. An image block can be divided into several sub-image blocks, and the size of these sub-image blocks can...

Abstract

The invention discloses an image decoding and coding method, device and system. A coding terminal carries out singular vector decomposition on a forecasting block corresponding to an image block to be coded, and feature vector matrixes U and V of the forecasting block are obtained; residual error data are coded according to the feature vector matrixes U and V, and the residual error data are pixel values of the image block to be coded and the difference between the pixel values of the corresponding forecasting block. By means of the image decoding and coding method, device and system, the mark load of a coding code flow can be lowered.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image encoding and decoding method, device, and system. Background technique [0002] In order to minimize the bandwidth required to transmit video data, for example, the video data can be compressed by using an intra-frame compression method or an inter-frame compression method, wherein the inter-frame compression method is usually an inter-frame compression method based on motion estimation. The decoding process specifically includes: the encoder divides the image block to be encoded into several sub-image blocks of equal size, and for each sub-image block, searches the reference image for the image block that best matches the current sub-image block as the prediction block, and then Subtract the sub-image block from the corresponding pixel value of the prediction block to obtain the residual, and perform entropy coding on the value obtain...
