数字水印技术的matlab实现，一个简单的水印算法，注意自己修改图片名(Digital watermark technology matlab to achieve a simple watermarking algorithm, pay attention to their own to modify the name of the picture)

基于稀疏表示的卡通纹理分解程序，能完成卡通纹理的分解(The program can complete that texture based on sparse decomposition process that cartoon, cartoon texture to complete the decomposition.)

说明：  《visual C++ 开发经验技术宝典》图像锐化处理，主要是将图像的亮度增加，颜色的鲜艳感增强。("Visual C++ development experience Technical Collection," Image sharpening, mainly to increase the brightness of the image, bright sense of color enhancement. )

本程序是基于Matlab的米粒图像的分割、计数以及周长、面积、形状因子等参数的计算。图像分割是基于腐蚀膨胀算法，选用边界跟踪法计算周长，程序代码清晰明了，对于参数的计算速度较快，且参数计算精度较高。(This procedure is based on the Matlab image segmentation grain of rice, counting and perimeter, area, shape factor and other parameters of the calculation. Image segmentation is based on the corrosion expansion algorithm, the choice of boundary tracking method perimeter, code clarity, the parameter calculation is faster and higher precision parameters.)

基于Canny算子检测图像边缘，其中含有非极大值抑制功能。(Based on Canny operator edge detection image, which contains a non-maxima suppression.)

量化离散余弦变换系数的程序实现及其效果的检测。过程中使用了8x8的分块方法。首先计算每块的离散余弦变换（DCT)；然后量化了DCT的系数； 最后进行了反离散余弦变换(iDCT). 程序中还可以设定缩放系数。(Quantify the discrete cosine transform coefficients procedure and its effect detection. The process used in the 8x8 sub-block method. First calculate the block discrete cosine transform (DCT), quantization of the DCT coefficient Finally, the inverse discrete cosine transform (iDCT) program can also set the scaling factor.)

基于小波变换的图像去噪处理，通过学习小波变换的方法实现对图像的去噪处理，达到所预期的效果(Image denoising based on wavelet transform, realize image denoising by wavelet transform learning method, to achieve the desired effect)

对图像采用DCT变换后，进行图像去噪的算法(Image denoise by DCT)

说明：  标记分水岭分割算法，文档有讲解有实例，对学习者很有帮助。(Mark a watershed segmentation algorithm, the document has to explain with examples, helpful to learners.)

非常好的EM算法介绍,不妨去看看.The Expectation Maximization Algorithm A short tutorial(Very good introduction EM algorithm, may wish to go and see. The Expectation Maximization AlgorithmA short tutorial)
