我写的 关于图象的掩蔽蜮值JND的种算法,请多指教-I write on the image masking worm value of the 131 types of algorithm, please enlighten

基于DCT域的鲁邦水印算法，原始图像分块DCT变换，基于纹理掩蔽特性的块分类，产生水印并嵌入提取-Lupin based DCT domain watermarking algorithm, the original image block DCT, texture classification based on block masking characteristics, generate and embed a watermark extraction

主要讲解空间锐化滤波器，例如拉普拉斯算子滤波器，索贝尔滤波器、非锐化掩蔽和高提升滤波器以及一阶微分图像锐化。-Mainly to explain the spatial sharpening filter, such as the Laplasse operator filter, the Sobel filter, non sharpening masking and high lift filter and first order differential image sharpening
