makebatches
自己编写的一个大批量不同类别数据录入程序，并且为防止因为数据量太大导致程序运行缓慢，将其改写成分批小规模数据。方便了大规模数据处理慢带来的各种不变。(I have written a large quantities of different types of data entry procedures, and because the amount of data in order to prevent too much causes the program to run slowly, be rewritten into small batches of data. Facilitate the large-scale data processing slow and the various unchanged.)

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.
