How to generate edge.mat and seg.mat file?

Hello, 

Thank you very much for your hard work. When running the code, I found that two files ‘’xx-seg.mat‘’ and ‘’xx-edge.mat‘’  need to be used. If I want to use my own dataset（only contain color image and depth map）, would you please tell me how to generate ‘’xx-seg.mat‘’ and ‘’xx-edge.mat‘'?
