24 Apr 2014 Gabor filter Generates Gabor filters using bandwidth, aspect ratio, phase, wavelength and angle as parameters. Author: Gao Yang Jones, Jack

I would like to ask the following question. I have used this filter with an image of all ones (imgin = ones(100,100)).

I get an image that consists entirely of ones, although my original image has no edges. Could you please explain what am I doing wrong or is this the normal behaviour of this filter?

I am ver new to matlab and image processing, can someone please explain to me the mathematical and theoretical reasoning behind the following lines:
gb = gabor_fn(bw,gamma,psi(1),lambda,theta)...
+ 1i * gabor_fn(bw,gamma,psi(2),lambda,theta);

and the line
img_out_disp = sum(abs(img_out).^2, 3).^0.5;
% default superposition method, L2-norm

what is this superposition method? is that the standard formula for it?
