Edge Detection using Laplacian Filter

Laplacian Filter (also known as Laplacian over Gaussian Filter (LoG)), in Machine Learning, is a convolution filter used in the convolution layer to detect edges in input.

Ever thought how the computer extracts a particular object from the scenery. How exactly we can differentiate between the object of interest and background.

Well a simple baseline answer could be: Edge Detection.

Before diving into the mechanics of it, let’s understand why specifically edge detection.
