how to get colored output as shown above
is there any demo to explain the work of gabor filter
Agree with previous comments - this code needs comments and does not run without correcting deg2rad.
Also, filter size is incorrect if sigma_x and sigma_y are not equal.
No comments in the Code.
You should replace the function deg2rad by angs= ang_s * pi / 180. Otherwise it creates an error. deg2rad is not in matlab...
