ImageCompress(QRfenjie)

基于contourlet的图像压缩编码，其中包括计算PSNR值，压缩比和运行时间(Contourlet-based image compression coding, including the calculation of PSNR values, compression ratio and run-time)

介紹在AWGN頻道上bit error rate的推導過程。附有詳盡的圖解與算示。(Describes the AWGN channel bit error rate of the derivation. Accompanied by detailed diagrams and calculation shown.)

完整的SNIC的算法，可直接运行，无需其他操作(SNIC algorithm, can run directly)

用C语言编的万年历(C language series hefty almanac)

利用零树小波的概念，完成了对静态图像的编码与解码，经过调试的。(The use of the concept of zerotree wavelet completed on the static image encoding and decoding, after debugging.)

基于哈弗曼树的压缩软件，可压缩文字和位图。(Huffman tree based compression software, compressible text and bitmaps.)

说明：  这是一个常用的JPEG-LS编解码的C语言实现。(This is a commonly used JPEG-LS codec C language.)

这是一个练习使用位写入/写出的程序，利用bitio.c和bitio.h工具整合，可以向文本文件E:\bitio1.txt中读取和写入数个位，使用者可以通过调试功能进一步了解位写入写出的作用。进而给今后做数据压缩打下基础。(This is a practice using bit write/write program, using bitio.c and bitio.h tool integration, you can read and write several bits to the text file E: \ bitio1.txt, the user can pass Debugging function to further understand the role of bit write write. And then lay the foundation for future data compression.)
