中文说明：Log Polar就是所谓的极坐标变换，通过变换能将笛卡尔坐标系中的图像映射到极坐标系中。确切的来说我这里不算是Log Polar，因为Log Polar是将图像从（x,y）映射到(log(r),theta) 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
English Description：
Log Polar is called the transformation of polar coordinates, by changing images in Cartesian coordinates can be mapped to a polar coordinate system. I not Log for the exact Polar, because Log Polar is an image from the (x, y) is mapped to (log (r), theta), and I is the image from (x, y) is mapped to (r,theta). The principle is the same. Transformation formula is: x=r*COS (theta); y=r*sin (theta), where r is the polar RADIUS, Theta represents the polar angle. They should have learned in high school.
