Since Random walker is used for both segmentation as well as classification. But it works on supervised learning so is it better to comapre it with other segmentation techniques or classification techniques like SVM.
For classification:
“SVM has a better performance when there are too few labeled samples. But as the number of labeled data increases, random walks will surpass SVM very soon.”
