Class RidgeDetectionFilter

Namespace
Emgu.CV.XImgproc
Assembly
Emgu.CV.dll

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.
