I have to calculate the ROC which is a graph between TPR and FPR. TPR and FPR are calculated from this LINK. But I am not understanding how do I plot ROC with it. As ROC is dependent upon the threshold values to plot between TPR and FPR. But FPR and TPR taken from this link are independent of threshold values. Kindly guide me what should I do to plot ROC?

The answered, which I have provided (manual process for non supervised classification algorithm), when I was very beginnner on MATLAB. There are other smart ways to do the same by buidling confusion matrix. Get the individually ROC points for same threshold values for multiple images. please refer the TOM paper to get the understanding of ROC analysis
I have provided another answer (on ROC), please check, it may be OK.

I had followed this way, when I did image segmentation work (unsupervised)
