PADFormer: Pose-agnostic Anomaly Detection from Sparse View Images
Ruiqi Wang, Yiming Qian, Fenggen Yu +4
Pose-agnostic Anomaly Detection (PAD) remains challenging as anomalies can appear under arbitrary viewpoints, requiring methods to handle significant pose variations. Existing appr…
DPA-Net: Structured 3D Abstraction from Sparse Views via Differentiable Primitive Assembly
Fenggen Yu, Yiming Qian, Xu Zhang +4
We present a differentiable rendering framework to learn structured 3D abstractions in the form of primitive assemblies from sparse RGB images capturing a 3D object. By leveraging…
Test-Time Adaptation for Point Cloud Upsampling Using Meta-Learning
Ahmed Hatem, Yiming Qian, Yang Wang
Affordable 3D scanners often produce sparse and non-uniform point clouds that negatively impact downstream applications in robotic systems. While existing point cloud upsampling ar…
Point-TTA: Test-Time Adaptation for Point Cloud Registration Using Multitask Meta-Auxiliary Learning
Ahmed Hatem, Yiming Qian, Yang Wang
We present Point-TTA, a novel test-time adaptation framework for point cloud registration (PCR) that improves the generalization and the performance of registration models. While l…
RoSI: Recovering 3D Shape Interiors from Few Articulation Images
Akshay Gadi Patil, Yiming Qian, Shan Yang +3
The dominant majority of 3D models that appear in gaming, VR/AR, and those we use to train geometric deep learning algorithms are incomplete, since they are modeled as surface mesh…
Learning to Recover Spectral Reflectance from RGB Images
Dong Huo, Jian Wang, Yiming Qian +1
This paper tackles spectral reflectance recovery (SRR) from RGB images. Since capturing ground-truth spectral reflectance and camera spectral sensitivity are challenging and costly…
Inference Time Evidences of Adversarial Attacks for Forensic on Transformers
Hugo Lemarchant, Liangzi Li, Yiming Qian +2
Vision Transformers (ViTs) are becoming a very popular paradigm for vision tasks as they achieve state-of-the-art performance on image classification. However, although early works…
HAL3D: Hierarchical Active Learning for Fine-Grained 3D Part Labeling
Fenggen Yu, Yiming Qian, Francisca Gil-Ureta +3
We present the first active learning tool for fine-grained 3D part labeling, a problem which challenges even the most advanced deep learning (DL) methods due to the significant str…
A Reliable Online Method for Joint Estimation of Focal Length and Camera Rotation
Yiming Qian, James H. Elder
Linear perspectivecues deriving from regularities of the built environment can be used to recalibrate both intrinsic and extrinsic camera parameters online, but these estimates can…
Glass Segmentation with RGB-Thermal Image Pairs
Dong Huo, Jian Wang, Yiming Qian +1
This paper proposes a new glass segmentation method utilizing paired RGB and thermal images. Due to the large difference between the transmission property of visible light and that…
