多媒体资源库图像自动压缩处理技术分析

The analysis of image automatic compression treatment technology in multimedia resource library

本文主要介绍了使用JPEG2000标准,构造系统框架,自动完成多媒体资源库中图像压缩处理的技术。从标量量化的角度出发,先对原始图像进行预处理,然后采用小波变换技术、Otsu算法、码字快速搜索算法、PCRD优化算法进行编码,得到较好的实验结果。

This article mainly introduces the standard of using JPEG2000, constructing system framework, the technology of auto completing image compression in multimedia resource library. From the scalar quantization point of view, first the primary image is made pretreatment, and then adopt wavelet transform technology, Otsu algorithm, yard word speediness research algorithm, PCRD optimization algorithm to encode, to get a better experiment result.
