Class RidgeDetectionFilter

Applies Ridge Detection Filter to an input image.

Implements Ridge detection similar to the one in Mathematica 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
