Problems solved by technology

However, the coefficient elimination technology is not a method defined by the HEVC standard. The performance of the existing coefficient elimination methods cannot be considered within the HEVC cost calculation system, resulting in uncontrollable distortion of the encoded image using the existing coefficient elimination methods.

Abstract

The invention relates to the technical field of image compression, and provides an encoding coefficient elimination method, which is compatible with an HEVC standard encoder, and comprises the following steps: S1, solving a threshold value according to a threshold value judgment formula, S2, if the coding quantization coefficient in the standard inverse quantization process is larger than the threshold value, reserving the coding quantization coefficient, and S3, if the coding quantization coefficient in the standard inverse quantization process is smaller than the threshold value, resetting the coding quantization coefficient. The method can be regarded as a redundancy elimination process of the coding coefficient, the coding efficiency including the coding speed, the compression ratio and the like can be effectively improved, and the original coding performance and effect are not damaged.

Description

technical field [0001] The present invention relates to the technical field of image compression, in particular to a coding coefficient elimination method and an improved HEVC coding method. Background technique [0002] HEVC (High Efficiency Video Coding) is a JCT-VC (Joint Collaborative Team) reorganized by VCEG (Video Coding Experts Group) and MPEG (Moving Picture Experts Group) in April 2010. on Video Coding (Video Coding Joint Group), jointly developed a new generation of video coding standards. As the next-generation mainstream video coding standard, HEVC is developed on the basis of the H.264 standard. It has greatly improved compression efficiency, parallel processing capabilities, and network adaptability. [0003] The HEVC standard encoder is mainly oriented to consumer application scenarios, specifically reflected in the fact that it is more suitable for use in high bit rate, high image quality application scenarios. For low-bit-rate or even extremely low-bit-ra...
