Efficient LoFTR: Semi-Dense Local Feature Matching with Sparse-Like Speed

1 code implementation7 Mar 2024 Yifan Wang, Xingyi He, Sida Peng, Dongli Tan, Xiaowei Zhou

Furthermore, we find spatial variance exists in LoFTR's fine correlation module, which is adverse to matching accuracy.

Detector-Free Structure from Motion

1 code implementation27 Jun 2023 Xingyi He, Jiaming Sun, Yifan Wang, Sida Peng, QiXing Huang, Hujun Bao, Xiaowei Zhou

We propose a new detector-free SfM framework to draw benefits from the recent success of detector-free matchers to avoid the early determination of keypoints, while solving the multi-view inconsistency issue of detector-free matchers.

Reconstructing Hand-Held Objects from Monocular Video

no code implementations30 Nov 2022 Di Huang, Xiaopeng Ji, Xingyi He, Jiaming Sun, Tong He, Qing Shuai, Wanli Ouyang, Xiaowei Zhou

The key idea is that the hand motion naturally provides multiple views of the object and the motion can be reliably estimated by a hand pose tracker.

Modeling Indirect Illumination for Inverse Rendering

1 code implementation CVPR 2022 Yuanqing Zhang, Jiaming Sun, Xingyi He, Huan Fu, Rongfei Jia, Xiaowei Zhou

The key insight is that indirect illumination can be conveniently derived from the neural radiance field learned from input images instead of being estimated jointly with direct illumination and materials.
