Octree

基于ransac的椭圆检测，对于一组随机的椭圆点，可以得到椭圆参数，检测精度高。(Based ransac ellipse detection, for a group of random elliptic points, you can get an ellipse parameters, high detection accuracy.)

说明：  灰图像三级小波分解，以lena图像为例。(Gray image 3 wavelet decomposition to lena image as an example.)

将压缩感知应用到图像分类方面，有详细的源码，下载就能运行(failed to translate)

说明：  ROC曲线函数,横轴为虚警概率，纵轴为检测概率(ROC curve function, the horizontal axis is false alarm probability, and the vertical axis is detection probability)

说明：  灰度直方图双峰法分割，传统的分割方法。适合初学者学习。(Bimodal histogram segmentation method)

引导滤波器，在引导图像的引导下对输入图像进行滤波，这种新型滤波器对边缘的保持很好，而且运行计算量和核的大小无关(Guide filters, under the guidance of the guide image filtering the input image, the edge of this new type of filter to keep well and run the calculation regardless of the size and nuclear)

说明：  基于各向异性扩散方程的一款经典的ＳＡＲ图像相干斑噪声抑制的算法实现，可以直接用的，效果很好！(Anisotropic diffusion equation based on a classic SAR image speckle noise reduction algorithm can be directly used, very good!)

利用改进的“参考白”算法对彩色图像进行光照补偿(Using improved "reference white" algorithm to compensate illumination of color image.)

说明：  powell刚性图像配准，c++代码，通过查找非相关方向进行配准.(Polwell rigid image registration, c++ code, by looking for non-related directions for registration.)

非局部平均，用来去除灰度图里面的噪声，效果明显(Probability Non-Local Means)
