Very nice ! It works fine.
I have a question:
If I want to apply for Uh=.4, Ul=.04 for 64 by 64 mask size, then how can I modify the code? Moreover which paper/journal has been followed when implementing this, please mention also.

Thanks in advance.

Hello,
I have a problem about commenting gabor results.I want to classify the images into 4 groups.Firstly,I used GLCM method for extraction image texture.And then I gave it ANN,k-NN and SVM.Instead of GLCM,I want to use Gabor Wavelet results.When I applied the code an image I found 64*64 GT matrice for each image.So,could you let me know how I can give these result into classifier input?

Regards,

Thanks for this submission.

I have a question about the equation used: why did you subtract 'exp ( -0.5 * Delt2 )' to the modulation component? I have never seen it before.

Thanks.

I found the answer of my previous question:

"The second term compensates for the dc-value of the kernel, to avoid unwanted dependence of the filter response on the absolute intensity of the image."
From "Distortion Invariant Object Recognition in the Dynamic Link Architecture"
