OpenCVForUnity.XimgprocModule.ContourFitting Class Reference

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...

Detailed Description

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.
