Generate Oversegmentation with OWT-UCM Procedure

There are two types of oversegmentations generated by different edge detectors: Structured Edge and Pointwise Mutual Information. We provide scripts to generate oversegmentations, respectively.

SE-OWT-UCM

1. Generate edges using Structured Edge detector. Edge files shall be put under voc12/edge or coco/edge folder.
2. Download and extract the toolkit here which combines tools from:
   • Berkeley Segmentation Resources (BSR)
   • Multiscale Combinatorial Grouping (MCG)
   • Piotar Dollar's edge detection toolkit
3. run generate_se_owt_ucm.m

PMI-OWT-UCM

1. Download PMI Edge detector.
2. move generate_pmi_owt_ucm.m under crisp-boundaries/Code folder.
3. run generate_se_owt_ucm.m.
