这是一个基于LZARI算法的数据压缩的类.Haruhiko Okumura 于1989年7月4日用c语言写实现了这个算法.但是上面用到了一些全局或静态的变量,在MFC下用起来很不方便.我把它改写成了一个c++类,使它可以方便的压缩和解压缩,更重要的是,我新增加了两个接口,这个类可以压缩/解压缩一段内存缓冲区,而不仅仅是文件. 一共提供了5个对外接口: -LZARI algorithm based on the type of data compression. Haruhiko SAP in 1989, July 4 c language daily wrote realization of this algorithm. But above uses some static or global variables, using the MFC which are very convenient. I rewrite it became a c categories, it can convenience compression, but more importantly, I added two new interface, the class can compression/decompression period memory buffer, and not just paper. A total of five external interface :

这个是我前一段时间在国外网站上找到的16-bit的霍夫曼编解码器。我们常用的都是8-bit的，希望这个对大家有用。尤其是对医学图像，因为其有8位，12位，16位等。-i got this 16-bit huffman codec from abroad website. we usually use 8-bit huffman codec. this source code is especially useful for medical image process.
