Amplitude Thresholding compression method used here in for ECG signal compression as presented on paper entitled as ECG signal compression with reconstruction via cubic spline approximation by Olga Malgina, Jana Milenkovi, Emil Plesnik, Matej Zajc, Andrej Koš ir and Jurij F. Tasi.

upx解压，演示upx解压的程序源码，仅供参考。(upx unpack，show upx unpack program source code)

文件的解压缩。添加文件unzip.h、unzip.cpp、zip.h、zip.cpp，调用对应函数进行压缩和解压。压缩格式为zip；压缩之后的文件可以用winrar等程序打开。(File decompression. Add file unzip.h, unzip.cpp, zip.h, zip.cpp, call the corresponding function for compression and decompression. Compression format is zip the file after compression can be opened by winrar.)

基于类函数形函数的参数化建模方法，适用于气动设计和优化(Class/Shpae Transform method)

huffman编码用于图像的压缩和解压，很好用的，可以用于各类图像的处理(huffman coding for image compression and decompression, useful, and can be used for all kinds of image processing)

常用图像压缩编码码matlab实现。包括：DM编码、变换编码（FFT和DCT）、算术编码、行程编码、Huffman编码、线性预测编码和一个近似的JPEG编码过程。非常适合入门用户实践。(Commonly used image compression coding matlab code to achieve. Including: DM coding, transform coding (FFT and DCT), arithmetic coding, Run-Length Coding, Huffman coding, linear predictive coding and a process similar to JPEG encoding. Very suitable for the practice of entry-users.)

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

说明：  文件中有两个编码程序，一个是简单的游程编码仿真实现，另一个是图像的游程压缩编码实现(There are two coding programs in the file. One is a simple run-length coding simulation implementation, the other is the image run-length compression coding implementation.)

说明：  上载蜂窝网无线定位遗传算法，希望大家相互交流学习。(Upload cellular wireless location genetic algorithm, hope that we learn from mutual exchanges.)

代码基于MATLAB平台完成，能够对图片进行压缩处理(Code based on the MATLAB platform, can carry on the compression processing to the image)
