Would you please kindly help me on the following 2 questions?
1. There are two methods/applications in ref: Grid Graph and Nearest Neighbor Graph. For grid graph, the input is the image. For NN Graph, the input can be the feature of each pixel. I can't find the NN Graph method in ref and your code. Do you know if there is such code publicly available?
2. for the parameters, how to correspond yours with the ones in ref? say, sigma, threshold(you use .5 while ref use 100-300)?
