Class for ContourFitting algorithms. ContourFitting match two contours $inline formula$ and $inline formula$ minimizing distance $block formula$ where $inline formula$ and $inline formula$ are Fourier descriptors of $inline formula$ and $inline formula$ and s is a scaling factor and $inline formula$ is angle rotation and $inline formula$ is starting point factor adjustement

Provided methods

`fn estimate_transformation( &mut self, src: &dyn ToInputArray, dst: &dyn ToInputArray, alpha_phi_st: &mut dyn ToOutputArray, dist: &mut f64, fd_contour: bool ) -> Result<()>`

Fit two closed curves using fourier descriptors. More details in PersoonFu1977 and BergerRaghunathan1998

Parameters

src: Contour defining first shape.
dst: Contour defining second shape (Target).
alphaPhiST: : $inline formula$ =alphaPhiST(0,0), $inline formula$ =alphaPhiST(0,1) (in radian), s=alphaPhiST(0,2), Tx=alphaPhiST(0,3), Ty=alphaPhiST(0,4) rotation center
dist: distance between src and dst after matching.
fdContour: false then src and dst are contours and true src and dst are fourier descriptors.

C++ default parameters

dist: 0
fd_contour: false
