本源码直观演示了音频ADPCM解压压缩算法 可手动数入数据,点击压缩解压按扭即可显示压缩解压的结果!-The source of the audio visual presentation ADPCM compression algorithm can extract the data manually into the number, click the button to display the compressed compression decompression decompression results!

基于改进K-means的压缩IP 由于k-means本身受异常点影响较大，这里采用迭代k-means的方法，降低异常点的影响，减少计算量和提高聚类数目的灵活性。并添加合并异常聚类方法，提高聚类的均匀性-K-means based on improved compression IP As k-means itself is influenced by outliers, where an iterative k-means method to reduce the impact of outliers, reducing the number of cluster computing capacity and enhanced flexibility. And add the combined abnormal clustering method to improve the uniformity of clustering

基于块方向的图像无损压缩代码，压缩包解压时不能有密码，不含res和DEBUG-Block-based direction of image lossless compression code, when extracting compressed package should not have a password, non-res and DEBUG
