固定压缩率算法的开发及实现

Development and Implementation of Fixed Compression Ratio Compression Algorithm

本文提出一种固定压缩率的算法。本文算法利用数据的概率分布特性,使用变换、量化等技术,实现固定压缩率的压缩。该算法结构简单易于实现,可方便地访问被压缩的数据。实验证明,该算法在减少存储器成本的情况下仍能使系统保持优良的性能。

This paper presents a new fixed compression ratio compression algorithm. The proposed algorithm implement a compression with low-complexity, fixed compression ratio and random access capability, using Hadamard transform, scalar quantization. Experiments show that, the algorithm keeps good system quality with memory reduction.
