DCT-for-image-compression-
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.))
