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. -This is a JPEG encoding & decoding program of still image. It does not use level shifting.

C是C++的基础，C++语言和Ｃ语言在很多方面是兼容的。因此，掌握了Ｃ语言，再进一步学习C++就能以一种熟悉的语法来学习面向对象的语言，从而达到事半功倍的目的。- C++ language and C language in many respects, are compatible. Therefore, the master of the C language, a further C++ will be able to study in a familiar with the study of grammar to object-oriented language, so as to achieve the purpose of a multiplier.
