This is 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.

Haskell 中文教程1-3章
说明： Haskell 中文教程1-3章(flw译)
纯粹的函数型编程语言。以著名逻辑学家 Haskell B. Curry 的名字命名。
最初的目的是想要设计出满足下面这些要求的语言：
1，它必须能够适合教学、研究、应用开发，包括一些大系统的构造。
2，它必须能够使用形式语言来准确描述。
3，它必须是自由免费的，任何人只要愿意都可以获取、使用和再次发布它。
4，它必须建立在大家一致认可的基础上。
5，它应该能够消除目前的函数型编程语言的差异。
(Haskell Chapter Directory 1-3 (flw translation) purely a function-based programming language. Famous applicability Haskell B. Curry named. The initial aim was to get below designed to meet the language requirements : 1, it must be suitable for teaching, research, application development, including the construction of large-scale systems. Two, it must be able to use formal language to accurately describe. 3, it must be free free of charge, to anyone who can access, use and release it again. 4, it must be built on consensus on the basis of recognition. 5, it should be able to eliminate the current function-type programming language differences.)
