Hey thank you for this code and I appreciate taking your time to read this. I came across your paper about PalmNet in (IEEE) and it sounded very intriguing. So I was just looking through your code and I had a doubt in it. Please correct me if my understanding of this is wrong.

functions_Gabor/getMostUsedWavelets.m
In the above file, there is this snippet of code:

    %get information of corresponding wavelet
    currX = sortRes(ind, 4);
    currY = sortRes(ind, 5);
    currO = sortRes(ind, 6);
    
    %check if current wavelet at current position already
    %used
    if (tmpRes(currO).value(currY, currX) == 1)
        %increment counter
        ind = ind + 1;
        continue
    end %if (tmpRes(currY, currX, currO)

I assume it refers to this line from the paper:

Then, for each filter in Ga, we count the number of corresponding responses in sm, considering each filter at most once for each position (x, y) in the ROI.

But, doesn't sortRes contain a unique combination of O, X and Y? What I'm trying to say is in tmpRes, there'd be no value equal to 1 when that condition is being checked and that combination of O, X and Y would have never appeared before.

Please let me know if my understanding is wrong. Thank you for the code and once again I appreciate your time.

thanks for your best contribution, I am very interested in your work. I am a beginner and tried to sort out your code, but I couldn't find the content of the network structure part. Can you help me point out the file part of the code about the palmnet network structure.Thanks

Hello, may I ask you a question? In the "searchGaborOrientation" code, on line 53, why do you subtract the centers from 180?Don't use 180 minus centers just the right bin?

Hello, what does countW stand for in "getMostUsedWavelets"? Why is it capped at 10,000?

In Tongji database,the EER is similar with paper . But in other database such as IITD,Casia. The EER is
much higher than paper about 3%. Do I need to tuning the parames?

Hello, I am a little confused about the paper. After getting Sm, how to extract 5 filters, could you please explain in detail?Thank you very much!
