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"

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.

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,
