 /** @brief  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.
