一种基于可逆信息隐藏的的无损鲁棒数字水印模型的研究(Study on framework model of lossless robust digital watermarking based on reversible data hiding)

数字图像处理，分水岭算法matlab源码,可以实现图像分割。(Digital image processing, watershed algorithm matlab source code, can achieve image segmentation.)

主要用来对矩阵进行奇异值分解，与MATLAB有同样的效果(It is mainly used to perform singular value decomposition on matrices and has the same effect as MATLAB.)

基于小波的图像多尺度方向特征提取，小波可使用 db4 (Based on wavelet multi-scale orientation of the image feature extraction, wavelet can be used DB4)

用lbp实现纹理特征提取，并分类说明: 一共有三个m文件，一个是lbp.m, 存放主要的lbp算法， 一个是getmapping,用以做算法的辅助函数， 一个是lbptest.m,存放着测试代码。 这三个文件需要放到同一个文件夹，并在文件夹中添加相应的图片， 具体的图片名字见lbptest.m的代码，运行lbptest.m可以查看结果。代码最后给出效果图 这三个文件是最传统的LBP方法，有256种。(With lbp achieve texture feature extraction and classification Description: A total of three m files, one is lbp.m, store the main lbp algorithm, One is getmapping, helper functions for doing arithmetic, One is lbptest.m, kept the test code. These three documents need to put the same folder, and add the appropriate folder, pictures, See lbptest.m specific name of the picture of the code, run lbptest.m can view the results. Finally renderings code These three documents are the most traditional LBP method, there are 256 kinds.)

根据RBM深度网络（Hinton，2006）进行MINST手写文字的分类器的训练，利用训练得到的权值制作了这个小程序，通过这个程序可以看出训练结果对数据集内的测试样本和训练样本都能进行很好的识别，但是对其他的手写字体识别就没有那么好了。(According to RBM depth network (Hinton, 2006) conducted MINST handwritten text classifier training, using the training to get the right value to produce this small program, this program can be seen through the results of the training data set and the training sample test samples are can be well identified, but on the other handwriting recognition is not so good.)

这是图像恢复中的盲反卷积迭代算法的matlab的源程序，对于学习数字图像有很大的好处！(This is image restoration in the Iterative Blind Deconvolution algorithm matlab source for the study of digital image has a lot of benefits!)

读取图片，用鼠标获取图片点坐标，输出坐标数据(Read the image, the image point coordinates obtained with the mouse, and output coordinate data)

这是一种很强的人脸检测程序，你可以试试，但我也不知是用什么方法。(This is a very strong face detection process, you can try, but I do not know in what ways.)

matlab源文件，可以实现利用matlab来画各种饼图，显示直观，对做数据分析和论文的同志会有帮助。(matlab source files, can be achieved using matlab to draw a variety of pie, intuitive display, and to do data analysis and papers comrades would help.)
