Instructions are in the README.md (and I think they might be in the paper as well):
Semantic: Semantic images come in two variants, semantic and semantic_pretty. They both include information from the point cloud annotations, but only the semantic version should be used for learning. The semantic images have RGB images which are direct 24-bit base-256 integers which contain an index into /assets/semantic_labels.json. Pixels where the data is missing are encoded with the color #0D0D0D which is larger than the len( labels ).
We even provide a function to get_index
in https://github.com/alexsax/2D-3D-Semantics/blob/master/assets/utils.py
May I know how to convert semantic labels from semantic.png in pano folder? These are rgb images, and I am curious about how to map them to unique semantic ids.
