Open3DIS: Open-vocabulary 3D Instance Segmentation with 2D Mask Guidance



... introduce Open3DIS, a novel solution designed to tackle the problem of Open-Vocabulary Instance Segmentation within 3D scenes.


... Recent advancements ... employing class-agnostic 3D instance proposal networks for object localization and learning queryable features for each 3D mask.


While these methods produce high-quality instance proposals, they struggle with identifying small-scale and geometrically ambiguous objects.


The key idea of ... method is a new module that aggregates 2D instance masks across frames and maps them to geometrically coherent point cloud regions as high-quality object proposals addressing the above limitations.


These are then combined with 3D class-agnostic instance proposals to include a wide range of objects in the real world.


... approach ... demonstrating significant performance gains in segmenting objects with diverse categories over the state-of-the-art approaches.
