三维最大Renyi熵的灰度图像阈值分割算法(Maximum Renyi entropy of three-dimensional gray-scale image segmentation algorithm)

K均值算法实现图像的分割，分割效果可以达到预期的效果(K-means algorithm to achieve image segmentation, segmentation results can be achieved the desired results)

1、可制作圆形、椭圆形、菱形、方形、三角形印章。 2、支持多种特效：翻转图形、透明处理、高斯模糊、亮度/对比度/饱和度/锐化/反相/海绵/陨化(磨砂)/浮雕等等。 3、可将制作好的印章保存至印章库。 4、支持1％－1000％比例缩放。 5、支持导出印章图片(透明图章使用GIF格式)。 6、支持预览/打印。(1, can be made round, oval, diamond, square, triangular seal. 2, supports a wide range of effects: flip graphics, transparent deal, Gaussian blur, brightness/contrast/Saturation/Sharpness/RP/sponge/meteorite of (Matte)/relief and so on. 3, can be saved to create a good seal of the Treasury seal. 4, in support of 1-1000 scaling. 5, support for export seal picture (stamp the use of transparent GIF format). 6, support for preview/print.)

图像处理入门教程，比较适合初学者，对于图像知识有所掌控，内容比较详细。(Image Processing Getting Started tutorial, suitable for beginners, more detailed image of knowledge has been the control.)

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.)

说明：  RM的编码过加性高斯白噪声信道（AWGN）后译码的C++ 实现程序，C语言产生高斯白噪声(RM of coded additive white Gaussian noise channel (AWGN) after decoding in C++ program, C language generated Gaussian white noise)

关于图像处理的一些基本操作，空间、频域图像增强，形态学处理，边缘检测等(About some of the basic image processing operations, space, frequency domain image enhancement, morphological processing, edge detection, etc.)

关于超分辨率图像恢复的凸集投影算法，运行结果正确。(code about super-resolution based on POCS)

基于小波变换的图像融合程序，低频采用加权平均，高频采用能量最大准则。(Based on wavelet transform image fusion program, low-weighted average, using high-frequency energy is the biggest criteria.)

说明：  旋转，利用双线性插值实现重采样，基于c++与opencv(Rotation, resampling by bilinear interpolation, based on C + + and opencv)
