DCT离散余弦变换编码和解码，利用vc对bmp图像实行变换，可以对变换和恢复后的结果进行保存和观看比较结果-the program of DCT coding and decoding.It is used to transform bmp to jpg.you can compare the original bmp to transformed jpg

本源码是用VC++6.0实现的，显示了BMP位图，并实现了快速的8*8的块的DCT和IDCT变换-the source of VC 6.0, showing a bitmap BMP, and achieve a rapid 8 * 8 block of DCT and IDCT transform

本程序是在VC++编译环境下，用纯C语言编写的2D-DCT变换，程序中用的是一个4*4的矩阵进行的变换，可以改为对一幅图像进行。运算结果正确，在Matlab中进行了检验，dct2()指令即进行DCT变换。有一定的参考价值。-This procedure is in VC++ compiler environment, written in pure C 2D-DCT transform, the program used is a 4 x 4 matrix for the transformat
