Cross-Modal Semi-Dense 6-DoF Tracking of an Event Camera in Challenging Conditions

1 code implementation16 Jan 2024 Yi-Fan Zuo, Wanting Xu, Xia Wang, Yifu Wang, Laurent Kneip

Vision-based localization is a cost-effective and thus attractive solution for many intelligent mobile platforms.

Robustness Verification for Knowledge-Based Logic of Risky Driving Scenes

no code implementations27 Dec 2023 Xia Wang, Anda Liang, Jonathan Sprinkle, Taylor T. Johnson

However, crucial decision issues related to security, fairness, and privacy should consider more human knowledge and principles to supervise such AI algorithms to reach more proper solutions and to benefit society more effectively.

CUR Transformer: A Convolutional Unbiased Regional Transformer for Image Denoising

1 code implementation journal 2023 Kang Xu, Weixin Li, Xia Wang, Xiaoyan Hu, Ke Yan, Xiaojie Wang, Xuan Dong

Based on the prior that, for each pixel, its similar pixels are usually spatially close, our insights are that (1) we partition the image into non-overlapped windows and perform regional self-attention to reduce the search range of each pixel, and (2) we encourage pixels across different windows to communicate with each other.

Passive Non-line-of-sight Imaging for Moving Targets with an Event Camera

no code implementations27 Sep 2022 Conghe Wang, Yutong He, Xia Wang, Honghao Huang, Changda Yan, Xin Zhang, Hongwei Chen

Non-line-of-sight (NLOS) imaging is an emerging technique for detecting objects behind obstacles or around corners.

Learning Incrementally to Segment Multiple Organs in a CT Image

no code implementations4 Mar 2022 Pengbo Liu, Xia Wang, Mengsi Fan, Hongli Pan, Minmin Yin, Xiaohong Zhu, Dandan Du, Xiaoying Zhao, Li Xiao, Lian Ding, Xingwang Wu, S. Kevin Zhou

In each incremental learning (IL) stage, we lose the access to previous data and annotations, whose knowledge is assumingly captured by the current model, and gain the access to a new dataset with annotations of new organ categories, from which we learn to update the organ segmentation model to include the new organs.

DEVO: Depth-Event Camera Visual Odometry in Challenging Conditions

no code implementations5 Feb 2022 Yi-Fan Zuo, Jiaqi Yang, Jiaben Chen, Xia Wang, Yifu Wang, Laurent Kneip

We present a novel real-time visual odometry framework for a stereo setup of a depth and high-resolution event camera.

Mixed-Stationary Gaussian Process for Flexible Non-Stationary Modeling of Spatial Outcomes

no code implementations17 Jul 2018 Leo L. Duan, Xia Wang, Rhonda D. Szczesniak

Different from a simple mixture of independent GPs, the mixture in stationarity allows the components to be spatial correlated, leading to improved prediction efficiency.

Gaussian Processes

Functional Gaussian Process Model for Bayesian Nonparametric Analysis

no code implementations10 Feb 2015 Leo L. Duan, Xia Wang, Rhonda D. Szczesniak

Gaussian process is a theoretically appealing model for nonparametric analysis, but its computational cumbersomeness hinders its use in large scale and the existing reduced-rank solutions are usually heuristic.
