本文是关于基于小波变换的图像压缩算法研究，首先介绍了图像压缩和小波变换理论，然后提出了改进的SPIHT算法和EZW算法。-This paper is based on the wavelet transform image compression algorithm, First of image compression and wavelet transform theory, and then proposed a plan to improve the SPIHT and EZW algo

Image Compression Based on Contourlet and No Lists SPIHT

SPIHT algorithm combined with Huffman encoding

ZPAV 是以小波，降维，剪切零树，运动估计，算术编码等算法为理论基础的音视频编解码协议，具有压缩率高，比特率低而稳定， 应用领域广，发展潜力大，延拓性好，复杂度适中，易于集成电路实现等特点，是理想的信源编解码协议。-ZPAV (H265) is audio-visual codec protocol, very different from H264/MPEG4, ZPAV (H265) basic algorithm is wavelets, SPIHT, BSW, MMW, .....
