Description: Huffman 这个名字,程序员们至少会联想到二叉树和二进制编码。的确,我们总以 Huffman 编码来概括 D.A.Huffman 个人对计算机领域特别是数据压缩领域的杰出贡献。我们知道,压缩 = 模型 + 编码,作为一种压缩方法,我们必须全面考虑其模型和编码两个模块的功效;但同时,模型和编码两个模块又相互具有独立性。-Huffman, programmers will at least think of a binary tree and binary coding. Indeed, we always Huffman coding to summarize D. A. Huffman personal computer areas, especially in the field of data compression outstanding contribution. We know that the compression encoding = model, as a compression method, we must take full account of two model and coding module effectiveness; But at the same time, model and coding module of two mutual independence.

Description: 实现基本JPEG的压缩和编码分三个步骤:
1. 首先通过DCT变换去除数据冗余;
2. 使用量化表对DCT系数进行量化;
3. 对量化后的系数进行Huffman编码。-Realize the basic JPEG compression and encoding is divided into three steps: 1. First of all, through the DCT transform to remove data redundancy 2. The use of quantization table of quantization DCT coefficients 3. Quantization coefficients after Huffman coding. Platform: |

Description: ) Compression using huffman code
-with a number of bits k per code word
-provide huffman table
Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.
