用CUDA并行处理方法改写的图像降噪算法，包括KNN,NLM,以及改进的NLM方法。配置环境适合VS2010+CUDA5.0,对使用CUDA的同学来说是很好的教材。(Image denoising algorithms including KNN,NLM and refined NLM run on CUDA, useful demo for who learns CUDA based parallel programming.)

利用梯度算法--最快下降梯度算法进行图像的边缘检测(Gradient algorithm- the fastest decline in the gradient algorithm for image edge detection)

包含实验图片，实验代码,对于从事数字图像处理工作有一定帮助(including experimental images and agrithms.It is benificial to image procecing workers.)

说明：  利用Hough变换实现半径未知的圆形物体的检测(Use Hough transform to achieve a circular radius of an unknown object detection)

用matlab开发的计算给定曲面点云的，高斯和平均曲率图(Matlab calculation developed by a given surface point cloud, the Gaussian and mean curvature map)

对采样得到的180幅断层图像进行重建，并针对其中的一幅图像进行处理，并且统计图像中颗粒的大小和数目！(Tomographic images of 180 samples obtained were rebuilt, and for which an image processing and image size and number of particles statistics!)

基于模拟退火的粒子群算法，主要是将模拟退火得概率问题用于粒子群，使其不易陷入局部最优(Simulated annealing particle swarm algorithm based on simulated annealing was mainly probability for PSO, it is not easy to fall into local optima)

基于spline的图像感兴趣区域提取，可用于基于区域的图像检索系统中。(spline- based region of interest image extraction, can be used for regional image retrieval system.)

经典的KSVD图像字典学习，matlab 代码，有注释，亲测可用(The classic KSVD image dictionary learning, matlab code, include notes, test available)

说明：  这是一个在vc6.0基于OpenCV的控制台程序，本例给出一个椭圆曲线拟合的例子，程序首先发现图像的轮廓，然后用椭圆逼近它。(This is a vc6.0 console based on the OpenCV procedures, in this case gives an example of elliptic curve fitting, the program first to discover the outline of the image, and then close it with an oval.)
