这是一个JPEG图像编码及解码的程序。它不使用级别…
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.

数据库库
应用背景嗯，这是我的学校工作之一。我认为它被设计为一个和，用户友好的程序。不同功能区域之间的组件和分离布局很好。关键技术这是做一些基本的GUI的东西（如菜单栏，标签，文本域，等）。从用户的数据将被存储在一个外部文件（文件I/O），用户可以搜索一本书根据一些关键词，搜索结果将被张贴在一个JDialog窗口。
