Duplicate masks for some objects #16

Open noelshin opened 7 months ago

noelshin commented 7 months ago

Thank you very much for your great work! I was visualising some instance masks and realised that there are cases where a single object has more than one instance mask (but they do not share the same instance id). For example, please check video id: 00015 in the validation split (i.e., objects for "nail_polish" and "bottle" have more than one mask). Is this expected behaviour? If I want to avoid loading multiple masks for the same object, what should I do?

Looking forward to seeing your reply! Gyungin

Dear @wjpoom,

The first author told that duplicated masks for an object are to allow difference categories for the object. But I think I found some masks that have duplicated masks with the same category, which seems a bit odd to me. Hope this helps in any way.

Kind regards, Noel
