16 Nov 2010 Gabor filter Generates Gabor filters using bandwidth, aspect ratio, phase, wavelength and angle as parameters. Author: Gao Yang

Very good implementation. And good job normalizing it! What I do notice is: you seem to do (a+b).^2 to get the modulus of the result. I thought for a complex number a+bj, you are supposed to do a.^2+b.^2 for the modulus. Lucky enough for this case, the cross term 2ab is simply zero because we are summing some trigonometric functions from 0 to 2pi.

Bad MATLAB implementation.

The code doing smooth well @ epsilon in range[0.05,0.1]. And what about HDR compression?
