Anything in Any Scene: Photorealistic Video Object Insertion

no code implementations30 Jan 2024 Chen Bai, Zeman Shao, Guoxiang Zhang, Di Liang, Jie Yang, Zhuorui Zhang, Yujian Guo, Chengzhang Zhong, Yiqiao Qiu, Zhendong Wang, Yichen Guan, Xiaoyin Zheng, Tao Wang, Cheng Lu

Our proposed general framework encompasses three key processes: 1) integrating a realistic object into a given scene video with proper placement to ensure geometric realism; 2) estimating the sky and environmental lighting distribution and simulating realistic shadows to enhance the light realism; 3) employing a style transfer network that refines the final video output to maximize photorealism.

Self-optimizing loop sifting and majorization for 3D reconstruction

no code implementations22 Apr 2021 Guoxiang Zhang, YangQuan Chen

Our proposed algorithm can compare the usefulness and effectiveness of different loops with the dense map posterior (DMP) metric.

3D Reconstruction Simultaneous Localization and Mapping

A metric for evaluating 3D reconstruction and mapping performance with no ground truthing

1 code implementation25 Jan 2021 Guoxiang Zhang, YangQuan Chen

It is not easy when evaluating 3D mapping performance because existing metrics require ground truth data that can only be collected with special instruments.

More Informed Random Sample Consensus

1 code implementation18 Nov 2020 Guoxiang Zhang, YangQuan Chen

In the hypothesis sampling step of the proposed method, data is sorted with a sorting algorithm we proposed, which sorts data based on the likelihood of a data point being in the inlier set.

LoopSmart: Smart Visual SLAM Through Surface Loop Closure

no code implementations4 Jan 2018 Guoxiang Zhang, YangQuan Chen

Sparse feature matching is used for visual odometry and globally camera pose fine-tuning when dense loops are detected, while dense surface alignment is the way of closing large loops and solving surface mismatching problem.
