The article discusses the challenges and advancements in 3D instance segmentation, specifically in an open-world environment. It highlights the need for identifying unfamiliar objects and proposes a method for progressively learning new classes without retraining. The authors present experimental protocols and splits to evaluate the effectiveness of their approach.
Highlights of the Practical Insights from the Article
1. Background:
3D Semantic Instance Segmentation: This involves the identification and labeling of objects in a 3D scene represented by point cloud or mesh.
Many applications rely on accurate object segmentation in the 3D space.
Datasets and deep learning techniques have greatly advanced in this area.
2. Disadvantage of Existing Techniques:
Vocabulary Limitation: Existing 3D instance segmentation techniques rely on fixed and predetermined sets of labels, limiting the recognition of unseen or unknown classes.
Unidentified objects sometimes get labeled as background elements and can go unrecognized.
However, open-world learning settings, where new classes can be progressively learned without retraining, have been explored in 2D object identification but not extensively in the 3D domain.
3. Implementation of Open-World 3D Instance Segmentation:
The goal is to recognize unfamiliar or novel objects as new data comes in, without requiring normalized sets of labels. It improves upon prior architectures through dealing with distinguishing known from unknown class labels and manipulate likelihood of unknown classes based on probability distribution diagram.
The research studies and analyzes practical open-world indoor 3D instance segmentation implementation with protocols and splits to effectively identify multi-class objects.
