class  cv::ximgproc::ContourFitting
 Class for ContourFitting algorithms. ContourFitting match two contours z_a and z_b minimizing distance

d(z_a,z_b)=\sum (a_n - s b_n e^{j(n \alpha +\phi )})^2

where a_n and b_n are Fourier descriptors of z_a and z_b and s is a scaling factor and \phi is angle rotation and \alpha is starting point factor adjustement. More...
