- 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

- JPEG压缩算法的核心是“视觉保真”原理,利用人类视觉系统特征进行处理,以达到最大图像数据压缩效果,实际上就是去除那些人眼不易觉察的信息。图像的空间频率对人的视觉至关重要,采用离散余弦变换可将图像分解成一组波,每个波有一个不同的空间频率,这样可以去除人类眼睛觉察不到的信息,而且还可使系统只保留重要的信息。-JPEG compression algorithm is the core of " visual fidelity" principle, the use of the
