WebThe LoG filter is an isotropic spatial filter of the second spatial derivative of a 2D Gaussian function. The Laplacian filter detects sudden intensity transitions in the image and highlights the edges. It convolves an image with a mask [0,1,0; 1,− 4,1; 0,1,0] and acts as a zero crossing detector that determines the edge pixels.
