国外写的knn-matting，图像抠图的源程序，有实例，可直接使用(knn-matting looking abroad to distinct the image layer, there are instances, can be used directly)

radon正反变换，可有效的去除抛物线型的多次波，内附主程序与数据，可以调试 运行(Radon positive and negative transformation, can effectively remove parabolic multiples, enclosing the main program and data, you can debug run)

SSR算法，自己已经测试过了，绝对可以使用！！！！而且我自己增加了直方图显示。希望能帮助到大家~~(SSR )

图着色问题（Graph Coloring Problem, GCP）又称着色问题，是最著名的NP-完全问题之一。路线着色问题是图论中最著名的猜想之一。(Graph coloring problem (Graph Coloring Problem, GCP), also known as coloring problem, is the most famous NP-complete problems. Line graph coloring problem is one of the most famous conjecture.)

经典的基于距离变换的图像细化的骨架提取方法。(Classic based on distance transform refining skeleton extraction method. )

用SIFT结合光流场进行图像配准，得到不错的效果(The image registration is carried out with SIFT combined with optical flow field, and good results are obtained.)

雷达信号处理一些相关操作，计算其距离向，方位向以及多普勒参数等。(radar signal processing)

说明：  一个改进的自适应canny算法，该方法采用改进的开关型中值滤波器对图像做去噪工作，再把整幅图像分割为若干子图像，最后在充分考虑全局以及各子图像的边缘梯度信息后，自适应地生成动态阈值。(The new Canny adaptive method divides image into sub-images,then determinates the thresholds automatically according to the whole image edge information and the sub-images edge information.)

方向加速法（Powell）是一种直接法，不用计算目标函数的梯度，仅通过比较目标函数的数值大小来移动迭代点就可以求出极值。(Powell use for registration)
