MATLAB-Arnold-tranform

提取特征点并匹配，有基于相关系数和最小二乘两种方法。(Extracting feature points and matching)

这是经典的SAR成像算法，包含了RDA CSA RMA三种常见的对于点目标的成像算法(This is classic SAR imaging algorithm, including the RDA CSA RMA three common for point target imaging algorithm )

人群密度估计，导入视频，生成一帧一帧的图片，并判断密度是否超过阈值，超过的报警。(Crowd density estimation, the introduction of video, generate a frame of pictures, and determine whether the density exceeds the threshold, more than the alarm.)

说明：  用水平集方法进行细胞图像的分割大家可以看看写的有点简单(level set method using cell image segmentation we can see a little bit simpler to write)

图形图象处理中的一个非常重要的特征的提取算法,zernike矩(Graphic image processing in a very important feature extraction algorithm, zernike Moment)

应用于计算机视觉领域，运用单应性矩阵信息将两幅图片合成为一张(Used in the field of computer vision, using homography information will be combined into a two picture)

该程序实现了相位编组法检测，可以将灰度缓慢变化的边缘提取出来(Realize the process of phase formation assay can be gray-scale changes in the edge of the slow extracted)

说明：  全变分模型主要是依靠梯度下降流岁图像进行平滑处理的模型,希望在图像的内部对图像进行平滑,使得相邻像素的差值较小(The total variation model is mainly based on the gradient descent flow year image smoothing model, hoping to smooth the image inside the image, so that the difference between adjacent pixels is small)

图片鱼眼畸变校正程序。用于处理图片桶形失真枕形失真。(Picture fisheye distortion correction program. Used for processing images barrel distortion pincushion distortion.)

Gabor滤波器的实现函数，与一般网上下载的不同，滤波效果更好，易于提取图像特征(Gabor filter implementation function, and general downloading different, better filtering, easy to extract image features)
