摘要

对整数DCT变换矩阵填充规则加以改进

得到一类新的整数变换基

称为"类整数DCT"变换基。从海量"类整数DCT"变换基中搜索出若干优选变换基

应用于MPEG4编解码实验

经实验测试和数据分析

结果表明优选"类整数DCT"变换基归一化正交矩阵与DCT变换的去相关性能相近

可替代整数DCT变换在图像编码中所起的作用。由于"类整数DCT"变换有完全快速算法

便于硬件实现

应用于图像编码

可降低编码器复杂度。

Abstract

Improve on the matrix filling rule of the integer DCT transform radix

a new type of integer transform radix was obtained

called variety integer DCT transform radix. Filtering the numerous of variety integer DCT transform radix

some optimum radix was obtained

and was applied to MPEG4 coding and decoding experiment

the analysis results of test data show that the normalized matrix of variety integer DCT transform radix have similar de-correlation characteristic with the original DCT matrix

and can replace functions of the integer DCT transform radix in image and video coding. Because variety integer DCT transform can be implemented by rapid butterfly algorithm completely

and can be implemented by hardware easily

applying to image and video coding

can reduce the complexity of coder and decoder greatly.
