Circular intensity filter

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.

We can write linear polarizations as E~ 0 =(Ex,Ey,0) (8) and choose the overall phase so that Ex and Ey are real numbers. If Ey =0 but Ex =/ 0, we have E~ =E 0 xˆei(kz−ωt) (9) with E0 = E~0 just a number now.Then, from Eq.
