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?
This is nice code!!
I used an image to find the area of the object.But in the excel file Area of the each object is shown.It would like to plot number of occurrence of same object size in graph...

Generates Gabor filters using bandwidth, aspect ratio, phase, wavelength and angle as parameters.
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?
