Blending 3D geometry and machine learning for multi-view stereopsis
2025
Vibhas Vats, Md. Alimoor Reza, David Crandall, Soon-heung Jung • Neurocomputing
GC-MVSNet++ improves the reconstruction quality of 3D scenes by introducing a novel cost-regularization network based on the principles of dense-connections. It produces competitive results to state-of-the-art MVSFormer++ paper without using Transformers.

Geometric Constraints in Deep Learning Frameworks: A Survey
2025
Vibhas Kumar Vats, David Crandall • ACM Computing Surveys
This survey examines how geometry can be integrated into deep learning frameworks for depth estimation and related computer vision problems. It presents a taxonomy of common geometry-based constraints, compares existing methods, and discusses future research opportunities.

HVPUNet: Hybrid-Voxel Point-cloud Upsampling Network
2025
Huyung Ha, Vibhas Kumar Vats, Soon-heung Jung, Alimoor Reza, David Crandall • ICCV
This paper presents an efficient method for point-cloud upsampling from sparse or incomplete 3D data. We propose Hybrid Voxels, which combine the efficiency of voxel-based processing with the precision of point-based representations, and build HVPUNet on top of this design. The resulting framework restores missing geometry, refines surface detail, and achieves strong accuracy with lower computational cost.
