基于DCT数字水印算法，希望能有用，用信噪比，检验鲁棒性(Digital watermarking algorithm based on DCT)

bm3d图像去噪算法，3个文件 用于处理灰度图像 x64(v 1.7.3 x64)

计算YUV文件的PSNR值，分别计算Y分量，U，V分量的PSNR值，还有宏块级的PSNR值(PSNR value calculated YUV file)

使用huffmandict函数对《小时代》进行编码，计算了整个编码的平均码长、最大码长、信息熵、编码效率的值(Use huffmandict function small time to encode the entire computing average code length coding, the maximum code length, information entropy coding efficiency values)

这三个小程序都是matlab的.m文件，分别实现用灰度变换的方法增强图像的对比度和直方图均匀化，模拟图像受高斯白噪声和椒盐噪声的影响。(The three procedures are Matlab. M documents, were used to achieve gray transform method to enhance the contrast of the image and histogram equalization. Simulation images by white Gaussian noise and the noise of Salt and Pepper.)
