[IP3-6-2] Edge detectors

The aim of sharpening filters is to highlight transitions in intensity (high frequency components) using different operators: directional (horizontal, vertical, diagonal) or isotropic (e.g. Laplacian Filter). Example of edge detectors include: Gaussian edge detector, Laplacian filter etc.
