代码说明:

  离散傅里叶变换,即DFT, 注意:FFT在matlab里有现成的函数可以用,它只是DFT快速实现的一种方法而已。(DFT: Discrete Fourier transform. )

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • JPEG_BaseLine_Encoder
    The JPEG compression scheme is divided into the following stages: 1. Transform the image into an optimal color space. 2. Adjust Aspect Ratio 16:9 3. Digitization Scheme 4:2:0. 4. Apply a Discrete Cosine Transform (DCT) to blocks of pixels, thus removing redundant image data. 5. Quantize each block of DCT coefficients using weighting functions optimized for the human eye. 6. Encode the resulting coefficients (image data) using a Huffman variable word-length algorithm to remove redundancies in the coefficients. 7. Byte Stuffing. 8. Header JFIF 9. JPG Data Store
