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 coefficie

DCT_JPEG
- 给予matlab的JPEG压缩程序,包含原始压缩图片,程序对灰度bmp图片进行JEPG编码,压缩成以0101形式的编码。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb,它利用人的视觉对色度不敏感的特点,减少一部分色度数据,以达到压缩。 JPEG采取多种编码方式,包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码,有很高的压缩比。在编码前,先对数据进行分块,离散余弦变换(DCT)及量化,保留能量大的低频信号,丢弃高频信号以达到压缩。-Given to th
