ProjFormer introduces geometric-projective transformer for point cloud completion

Researchers have introduced ProjFormer, a novel framework designed to improve point cloud completion by addressing the inherent sparsity and ambiguity in partial observations. This system utilizes a Projective Guided View Attention module to align 3D points with multi-view features through deterministic projection, ensuring geometrically consistent aggregation. Additionally, a geometry-aware routing network facilitates adaptive fusion of structural and observation-driven features for progressive refinement, leading to competitive performance and enhanced structural completeness.
