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

  • new-PR-controller
    为了验证PR控制器,加入了比例控制和谐振控制器功能性,对三次及技术次谐波对应控制其输出做出分析-(In order to verify the PR controller, the proportional control and the resonant controller functionality are added, and the output of the third and the technical sub-harmonics is controlled.)

    用小波分析对所给图象进行增强处理,增强过后的效果明显(To will carry on enhancement processing with the wavelet analysis to the image, enhancement from now on effect is obvious )
