org.opencv.ximgproc.RidgeDetectionFilter

public class RidgeDetectionFilter
extends Algorithm

Applies Ridge Detection Filter to an input image. Implements Ridge detection similar to the one in [Mathematica](http://reference.wolfram.com/language/ref/RidgeFilter.html) using the eigen values from the Hessian Matrix of the input image using Sobel Derivatives. Additional refinement can be done using Skeletonization and Binarization. Adapted from CITE: segleafvein and CITE: M_RF
