Rayleigh-approximation

利用DCT进行图像压缩（首先将图像分割成8×8的图像，对每个子图像进行DCT，这样每个子图像有64个系数，舍去50％小的变换系数，进行2：1的压缩。）(Using DCT for image compression (first image into 8 × 8 image, for each sub-image DCT, so that each sub-image by a factor of 64, rounding 50 of the small transform coefficients, the 2:1 compression.))

里面包含了大量的matlab的m文件，主成分、PLS等算法，还包括了傅里叶变换等海量代码，绝对好东西(Which contains a large number of matlab m-file, the main component, PLS and other algorithms, including Fourier transform mass code is absolutely a good thing)
