What kinds of ground-truth labels are required for MCG training? #24
Comments
Hi @qjadud1994, There are two learnt parts in MCG:
So in some sense it's "very little supervised" since it's "zero shot" on e.g. COCO, and the segmentation itself is not trained (heuristic on the hierarchy of regions given by the UCM) |
Thank you for your reply @jponttuset ! Then, in summary, "MCG requires object contour (boundary) labels for the training" is it right? |
Correct, but not on the target domain, just once completely class-agnosticly and then it transfers zero-shot to the datasets.
I don't get this. |
Thanks a lot @jponttuset ! Now, I understand about it. |
I currently survey various segment proposal methods.
However, I could not catch what kinds of ground-truth labels (e.g., segmentation map, object boundary) are required for MCG training because I'm not familiar with Matlab code :(
Also, some papers argue that MCG is an unsupervised method, is it right?
If anyone knows about this, please let me know.
