Multi-View Hierarchical Graph Neural Network for Sketch-Based 3D Shape Retrieval

arXiv CS.CV

ArXi:2604.18019v1 Announce Type: new Sketch-based 3D shape retrieval (SBSR) aims to retrieve 3D shapes that are consistent with the category of the input hand-drawn sketch. The core challenge of this task lies in two aspects: existing methods typically employ simplified aggregation strategies for independently encoded 3D multi-view features, which ignore the geometric relationships between views and multi-level details, resulting in weak 3D representation.
