Combining Deep Learning with Geometric Features for Image based Localization in the Gastrointestinal Tract

no code implementations11 May 2020 Jingwei Song, Mitesh Patel, Andreas Girgensohn, Chelhwon Kim

Considering these, we propose a novel approach to combine DL method with traditional feature based approach to achieve better localization with small training data.

A closed-form solution to estimate uncertainty in non-rigid structure from motion

no code implementations10 May 2020 Jingwei Song, Mitesh Patel

In this paper, we present a statistical inference on the element-wise uncertainty quantification of the estimated deforming 3D shape points in the case of the exact low-rank SDP problem.

Curved Buildings Reconstruction from Airborne LiDAR Data by Matching and Deforming Geometric Primitives

no code implementations22 Mar 2020 Jingwei Song, Shaobo Xia, Jun Wang, Dong Chen

To this end, we propose a new framework for curved building reconstruction via assembling and deforming geometric primitives.

Efficient two step optimization for large embedded deformation graph based SLAM

no code implementations20 Jun 2019 Jingwei Song, Fang Bai, Liang Zhao, Shoudong Huang, Rong Xiong

In this paper, we propose an approach to decouple nodes of deformation graph in large scale dense deformable SLAM and keep the estimation time to be constant.
