Problems solved by technology

However, since the kernel vector of ICT is not normalized, ICT must be combined with normalization to ensure energy conservation
When the modulus of each kernel vector of ICT, that is, the sum of the squares of each coefficient in the kernel vector, is n

Abstract

This invention discloses a quasi-energy conservation and transformation method and the device used in video or image compact by applying two-dimension transformation of not accurate energy conservation, data of different positions adopt a same orthonormalization process to reduce computation complexity and storage complexity for a code/decode device, which is not only used in video or image code/decode field but also used in other signal processes.

Description

technical field [0001] The present invention relates to an electrical digital data processing technology, in particular, to a method and device for quasi-energy conservation transformation applied to video or image compression. Background technique [0002] Traditional video coding standards such as H.261, H.263, H.26L, and H.264 standards formulated by the International Telecommunication Union ITU and MEPG-1, MPEG-2, and MPEG formulated by the International Organization for Standardization ISO's Motion Picture Experts Organization MPEG -4 and so on are based on the Hybrid Coding framework. The so-called hybrid coding framework is a coding framework that comprehensively considers prediction, transformation and entropy coding methods, and has the following main features: 1. Use prediction to remove redundancy in the time domain; 2. Use transformation to remove redundancy in the space domain; 3. Statistical redundancy is removed by entropy coding. [0003] The above-mentione...
