Huffman 编码是第一个实用的无损压缩编码技术，经过了多年的不断改进，已经形成了系统的理论和方法。目前主要有两种类型的Huffman编码方式，即静态Huffman编码和动态Huffman编码。Huffman编码有着广泛的应用，但是不再是压缩算法的全部，而是被当作最终的编码方法。(Huffman coding is the first practical lossless compression coding technology, after years of continuous improvement, has formed a system of theories and methods. There are currently two types of Huffman encoding, namely, static and dynamic Huffman coding Huffman coding. Huffman coding has been widely used, but the compression algorithm is no longer all, but rather be treated as the final coding.)
