描述了C++文件操作的操作方法 ios::app：　　　以追加的方式打开文件 ios::ate：　　　文件打开后定位到文件尾，ios:app就包含有此属性 ios::binary： 　以二进制方式打开文件，缺省的方式是文本方式。两种方式的区别见前文 ios::in：　　　 文件以输入方式打开 ios::out：　　　文件以输出方式打开 ios::nocreate： 不建立文件，所以文件不存在时打开失败　 ios::noreplace：不覆盖文件，所以打开文件时如果文件存在失败 ios::trunc：　　如果文件存在，把文件长度设为0 -Describes the C++ file operations How ios:: app: an additional way to open the file ios:: ate: File opened locate end of file, ios: app will contain this attribute ios:: binary: open the file in binary mode , the default way is to text mode. The difference between two ways to see above ios:: in: file to open the input mode ios:: out: file to output mode open the ios:: nocreate: do not create the document, so when you open the file does not exist failed ios:: noreplace: Do not overwrite file, so when you open the file if the file exists failed ios:: trunc: If the file exists, the file size set to 0

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.
