How to obtain proposals shown in the paper?

[cnut1648]

Hi, I would like to thank you for sharing the code with us.
I have a question, I have downloaded MCG Proposals for PASCAL VOC 2012 in here and in each .mat file there are

• superpixels
• labels
• scores
  I visualize the superpixels and it looks like this
  
  I wonder what should I do to obtain segmentation like the rightmost column in Fig. 2 of MCG paper.
  

Thank you!

Or more specifically, from kmaninis/COB#4 it seems that to obtain a higher level segmentation we need to have a segmentation label to match. Therefore am I correct that we need first to have a segmentation model that can generate segmentation prediction? If so then is it correct to say that to obtain high-level segmentations like the one in Fig. 2 of the MCG paper the segmentation label is needed (as the segmentation model needs it)?

Dear author, how to generate mat file frim raw picture like below picture?
