CodedStereo: Learned Phase Masks for Large Depth-of-field Stereo

no code implementations CVPR 2021 Shiyu Tan, Yicheng Wu, Shoou-I Yu, Ashok Veeraraghavan

Conventional stereo suffers from a fundamental trade-off between imaging volume and signal-to-noise ratio (SNR) -- due to the conflicting impact of aperture size on both these variables.

InterHand2.6M: A Dataset and Baseline for 3D Interacting Hand Pose Estimation from a Single RGB Image

2 code implementations ECCV 2020 Gyeongsik Moon, Shoou-I Yu, He Wen, Takaaki Shiratori, Kyoung Mu Lee

Therefore, we firstly propose (1) a large-scale dataset, InterHand2. 6M, and (2) a baseline network, InterNet, for 3D interacting hand pose estimation from a single RGB image.

Epipolar Transformers

1 code implementation CVPR 2020 Yihui He, Rui Yan, Katerina Fragkiadaki, Shoou-I Yu

The intuition is: given a 2D location p in the current view, we would like to first find its corresponding point p' in a neighboring view, and then combine the features at p' with the features at p, thus leading to a 3D-aware feature at p. Inspired by stereo matching, the epipolar transformer leverages epipolar constraints and feature matching to approximate the features at p'.

Learning Patch Reconstructability for Accelerating Multi-View Stereo

no code implementations CVPR 2018 Alex Poms, Chenglei Wu, Shoou-I Yu, Yaser Sheikh

By prioritizing stereo matching on a subset of patches that are highly reconstructable and also cover the 3D surface, we are able to accelerate MVS with minimal reduction in accuracy and completeness.
