Description: 输入一段英文字符，试为该文中的每个字符编制相应的哈夫曼码。
（1）I：初始化（Initialization）。对输入的一段英文中的每个字符统计其权值，建立哈夫曼树；
（2）E：编码（Encoding）。利用已建好的哈夫曼树，对每个字符进行编码。
（3）D：译码（Decoding）。利用已建好的每个编码，对输入的一个由0、1组成的序列进行译码；
（4）P：印代码文件（Print）。将每个字符编的哈夫曼码和译码结果显示在终端上。
-Enter a period of English characters, try the text for each character corresponding Huffman code. (1) I: Initialization (Initialization). A section of the input English characters statistics for each value of its right to establish a Huffman tree (2) E: encoding (Encoding). Has been built using Huffman tree for each character encoding. (3) D: Decoding (Decoding). Use has been completed for each encoding, the input of a sequence consisting of 0,1 Decoding (4) P: Printing code files (Print). Will be allocated for each character code and the Huffman decoding results are displayed in terminal. Platform: |

Description: 问题描述]
利用哈夫曼编码进行信息通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求在发送端通过一个编码系统对待传数据预先编码，在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双向传输信息的信道），每端都需要一个完整的编/译码系统。试为这样的信息收发站写一个哈夫曼编/译码系统。-Description of the problem] use Huffman encoding of information and communication can greatly improve the channel utilization, reduce the information transmission time, lower transmission costs. However, this requires the sending end through a coding system for pre-treatment of mass data encoding, will be heard at the receiving end of the data decoding (recovery). For duplex channel (ie, two-way transmission of information can be channel), each client requires a full encoder/decoder system. Test for such information transceiver station to write a Huffman encoder/decoder system. Platform: |

Description: This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.
