Detailed Description

Creates a Laplacian of Gaussian filtered image.

In fact second derivative (Laplacian: of a smoothened version of the image, combined in a single filter operation: if r^2 = x^2 + y^2 z = r^2 / (2 * (sigma^2)) then LoG(x,y) = (1-z) * exp(-z) / (pi * sigma^4) http://homepages.inf.ed.ac.uk/rbf/HIPR2/log.htm
