The Laplacian is a 2-D isotropic measure of the 2nd spatial derivative of an image . The Laplacian of an image highlights regions of rapid intensity change and is therefore often used for edge detection (see zero crossing edge detectors).
The Laplacian operator is defined by: Laplace(f) = \dfrac{\partial^{2} f}{\partial x^{2}} + \dfrac{\partial^{2} f}{\partial y^{2}} |
