修改了冈萨雷斯《数字图像处理》中的区域生长法。本函数中含有三种选择种子点的方法：分别依据灰度值，种子点位置，交互式选择单个种子点。(Modified the region growing method described in "Digital Image Processing" . This function contains three options for the method of seed points: based on gray value, the location of the seed points, interactive selection of a single seed point. )

分别利用 Roberts、Prewitt和 Sobel 算子对原图像进行边缘检测和锐化。(Respectively use Roberts, Prewitt and Sobel operator on edge detection and sharpening the original image.)

小波包对信号的分解与重构在matlab中的应用，以及能量，频率(Wavelet packet decomposition and reconstruction of the signal in the application of matlab, and energy, frequency)

使用C++和CUDA编写的双边滤波器。在平滑图像的同时可以保持边界(Using bilateral filter the C++ and CUDA written. Boundary can be kept in the smooth image while)

给图像加椒盐和高斯噪声，以及空域滤波（中值和均值滤波）！(to Image pretzels and Gaussian noise, and the spatial filter (mean values and filter)!)

说明：  图像增强程序，经测试有一定效果。其中采用模糊增强算法，值得参考。(Image enhancement procedures, have been tested and have a certain effect. Which the use of fuzzy enhancement algorithm, it is also useful.)

说明：  MATLAB工具箱，《数字图像处理》冈萨雷斯版专用，网上不少人在找，这是我从国外网站下载的，贡献出来。(MATLAB toolbox, )

尺度空间sift算法的matlab实现，对理解算法步骤很有帮助(Scale space sift algorithm matlab to achieve an understanding of the steps of the algorithm helpful)

这是一个人脸识别系统，其中详细的给出了人脸识别软件的开发过程，应用MATLAB编程实现，是一个不可多得的好软件。(This is a face recognition system, which gives a detailed Face Recognition software development process. MATLAB programming is a very good software.)

迭代CT重建血管，希望对大家能够有所帮助(Iterative CT reconstruction of blood vessels, we want to be able to help)
