Researchers have introduced PASR, a novel framework for 3D shape retrieval from single, potentially occluded images. PASR distills knowledge from the DINOv3 foundation model into a 3D encoder, enabling alignment between pose-conditioned 3D projections and 2D feature maps. This approach formulates retrieval as an analysis-by-synthesis problem, where test-time optimization searches for the optimal shape and pose to reconstruct image features. The method demonstrates significant improvements over existing techniques in handling occlusions and offers multi-task capabilities including pose estimation and category classification. AI
