DTC

该程序实现了Baum-Welch算法，对于通信里面的调制解调有很大帮助，其次，该程序具有通用性。(The program achieved the Baum-Welch algorithm, for the communication modem inside helps a lot, and secondly, the program has the versatility.)

This software release consists of an implementation of the algorithm described in the paper: H. R. Sheikh, A. C. Bovik, and G. de Veciana, "An Information Fidelity Criterion for Image Quality Assessment Using Natural Scene Statistics," IEEE Transactios on Image Processing, in publication, May 2005.

DCT变换1、 提取彩色图像，将图像大小限制为512*512*3； 2、 提取彩色图像三个颜色分量的矩阵，每个矩阵单独处理； 3、 将矩阵分为8*8的块，做DCT变换； 4、 提取每个块的一部分DCT系数做IDCT变换，显示基本图像； 5、 再提取每个块的一部分DCT系数做DCT反变换，得到增强层1，与前一次得到的数据叠加，得到质量更好的图像。 (DCT transform)
