RGB图像格式转换为YUV格式。
根据RGB到YUV关系转化以及分量取平均值转换两种方法，以实例形式编程，不是子函数的形式。(RGB to YUV。
figure s style transform.)

jpeg_encode+decoderhojoon
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.

huffmam_decoding
the decoding of Huffman codes is shown. For the decoding the coding tree has to be constructed using the information which has to be transmitted as well.
Following that the input is read bitwise and for each 0 a left turn is taken and for each one a right turn until a leave is reached. In this case the value of the leave (usually a character) is output, continuing after that at the root.
