可以进行图像的DCT变换 说明程序虽小，但是是原创-Can explain the image DCT transform process is small, but it is original

基于数字的DCT编码 离散余弦变换 通过CC调试 能快速精确完成编码 -Number of DCT coding based on discrete cosine transform can be quickly and accurately through the CC completed debugging code

调用noissin.dat的数据，对其做一维DCT及逆DCT，研究对DCT的结果舍去不同点数后的重建情况-Call noissin.dat data, do their one-dimensional DCT and inverse DCT, the results of research on the DCT rounding after the reconstruction of different points
