Abstract

The invention discloses a data coding method and device based on an irregular template, electronic equipment and a medium. By applying the technical scheme of the invention, after the to-be-coded area is obtained, the to-be-coded area is subjected to template internal pixel matching and template matching by using various pre-designed irregular-shaped templates, so that a more compact coded data expression form is provided, and the coding efficiency is improved. And the problem of low quality of a decoded and reconstructed image caused by coefficient loss due to inaccurate prediction is solved.

Description

technical field [0001] The present application relates to data processing technology, in particular to a data encoding method, apparatus, electronic device and medium based on an irregular template. Background technique [0002] With the continuous popularization of image and video applications, video light compression technology is also constantly iterated and innovated. Common video light compression standards such as DSC, VDC-M, Apple ProRes and JPEG-XS are widely used in HDMI, DP and other display interface fields and image and video production fields, respectively. [0003] Among them, the main purpose of the general video light compression standard is to achieve 4-16 times data compression under the conditions of low delay, low complexity and subjective lossless. Taking the more general DSC1 coding standard as an example, the compression process mainly includes the steps of input and output, buffer slicing, prediction, quantization, reconstruction, entropy coding, rat...
