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.
