Question about GT-sampling #13

Open zoomkinseok opened 1 year ago

zoomkinseok commented 1 year ago

Thanks for the interesting research. I understand filtering the points that are occluded by objects in the GT-sampling step. However, in GT sampling, objects can be created in unexpected spaces. Is there a way to get rid of GT sampled objects if they are created behind walls or behind non-annotated objects? I wonder if this paper also took this situation into account.

thank you Minseok

Hi @zoomkinseok , As far as I know, it doesn't consider your questions. I'm curious why you want GT sampled objects not to appear behind non-annotated objects, I think this occlusion is a real situation.
