利用OPENCV库实现基于对图像的离散余弦变换，有详细的注解-OPENCV library using the image-based discrete cosine transform, with detailed comments

此程序用C语言，opencv语言共同写的离散余弦变换的程序，在程序中对离散余弦的变换是8*8分块的变换，以便后续处理。-This program written in C language, opencv language program of the discrete cosine transform, discrete cosine transformation in the program is 8* 8 block transform, for subsequent processing

离散余弦变换变换经典版，可以供大家参考和学习-Discrete Cosine Transform transform the classic version, for your reference and learning

基于DCT离散余弦变换的图像压缩程序，里面还有BDCT代码段。-DCT image compression based on discrete cosine transform procedures, there is also BDCT code.
