摘要
基于小波变换静止图像压缩提出一种快速算法。在兼顾压缩比和峰值性噪比的同时,采用离散小波变换的快速算法,对量化和熵编码两部分进行优化,提高了算法的快速性,并进行了实验验证。
A new still image compression fast algorithm coding based on wavelet transform is proposed. With compression ratio and PSNR the speediness algorithm of two dimension discrete wavelet transform is adopted, and the part of the quantization coding and the entropy coding is optimized in order to improve image compression efficiency. And its performance is proved by experiments.
