Abstract: Due to the difficulty in generating the effective descriptors which are robust to occlusion and viewpoint changes, place recognition for 3D point cloud remains an open issue. Unlike most of ...

Abstract: The task of 3D semantic scene graph (3D SSG) prediction in the point cloud is challenging since (1) the 3D point cloud only captures geometric structures with limited semantics compared to ...

GraphDreamer takes scene graphs as input and generates object compositional 3D scenes. Results of the first (coarse) and the second (fine) stage will be save to ...

MMGDreamer is a dual-branch diffusion model for scene generation that incorporates a novel Mixed-Modality Graph, visual enhancement module, and relation predictor. Feel free to contact Zhifei Yang ...
