这是一个实现了发表在CVPR2006的抠图算法。(This package contains an implementation of the matting algorithm described in the CVPR2006 paper.)

写成gauss-gamma双窗函数，计算含有相干斑噪声的sar图像的梯度(The gauss-gamma double window function is used to calculate the gradient of the SAR image with the speckle noise)

使用透视变换对图像进行畸变矫正，可以正常运行。(use Perspective transformation about image distortion correction )

用协方差方法估计AR模型参数,进而实现功率谱估计,()

本方法的种子点选取采用Harris角点法，阈值则通过云模型获得，对lena图像进行了较好的分割(The method selected seed points using Harris corner point method, the threshold is obtained through the cloud model, for better lena image segmentation)

半自动分割彩色图像的颜色相同区域，可以达到PS的魔棒效果(Semi-automatic segmentation of color images the same color region can reach the magic wand effect of PS)

说明：  n个点电荷电场线的matlab仿真 分别有1个 2个等（可以通过改变程序数字来得到相应的仿真结果）(Matlab simulation of N-point charge electric field lines)

将黑白图像转换成灰度级—邻域平均灰度级二维直方图(Black and white images will be converted into gray-scale- the average gray-scale neighborhood of two-dimensional histogram)

利用matlab控制摄像头，对图像实时进行二值灰度处理(Using MATLAB to control the camera, the image is processed with two value gray in real time)

说明：  短时傅里叶逆变换，参数一共有4个，hop， fs,源信号向量(Inverse short time Fourier transform)
