Semantic IDs for background ?

❓ Questions and Help

Hi ✋

When generating semantic images using ProcThor dataset, I encountered an issue where the backgrounds such as ground and walls didn't show any semantic id. Only foreground objects had semantic information. Is there any way available to extract semantic information on background?

Hey @jonghochoi,

Thanks for your interest in using Habitat.

Embedding semantics into the background objects requires an accompanying semantic texture or a second semantic mesh at this time. We do not currently have plans to provide this for ProcThor, but it could be authored on your side.

Please see HM3D semantics as an example.
