RoDLA: Benchmarking the Robustness of Document Layout Analysis Models

no code implementations21 Mar 2024 Yufan Chen, Jiaming Zhang, Kunyu Peng, Junwei Zheng, Ruiping Liu, Philip Torr, Rainer Stiefelhagen

To address this, we are the first to introduce a robustness benchmark for DLA models, which includes 450K document images of three datasets.

Skeleton-Based Human Action Recognition with Noisy Labels

1 code implementation15 Mar 2024 Yi Xu, Kunyu Peng, Di Wen, Ruiping Liu, Junwei Zheng, Yufan Chen, Jiaming Zhang, Alina Roitberg, Kailun Yang, Rainer Stiefelhagen

In this study, we bridge this gap by implementing a framework that augments well-established skeleton-based human action recognition methods with label-denoising strategies from various research areas to serve as the initial benchmark.

Navigating Open Set Scenarios for Skeleton-based Action Recognition

1 code implementation11 Dec 2023 Kunyu Peng, Cheng Yin, Junwei Zheng, Ruiping Liu, David Schneider, Jiaming Zhang, Kailun Yang, M. Saquib Sarfraz, Rainer Stiefelhagen, Alina Roitberg

In real-world scenarios, human actions often fall outside the distribution of training data, making it crucial for models to recognize known actions and reject unknown ones.

Elevating Skeleton-Based Action Recognition with Efficient Multi-Modality Self-Supervision

1 code implementation21 Sep 2023 Yiping Wei, Kunyu Peng, Alina Roitberg, Jiaming Zhang, Junwei Zheng, Ruiping Liu, Yufan Chen, Kailun Yang, Rainer Stiefelhagen

These works overlooked the differences in performance among modalities, which led to the propagation of erroneous knowledge between modalities while only three fundamental modalities, i. e., joints, bones, and motions are used, hence no additional modalities are explored.

S$^3$-MonoDETR: Supervised Shape&Scale-perceptive Deformable Transformer for Monocular 3D Object Detection

no code implementations2 Sep 2023 Xuan He, Kailun Yang, Junwei Zheng, Jin Yuan, Luis M. Bergasa, HUI ZHANG, Zhiyong Li

These methods typically use visual and depth representations to generate query points on objects, whose quality plays a decisive role in the detection accuracy.

Open Scene Understanding: Grounded Situation Recognition Meets Segment Anything for Helping People with Visual Impairments

1 code implementation15 Jul 2023 Ruiping Liu, Jiaming Zhang, Kunyu Peng, Junwei Zheng, Ke Cao, Yufan Chen, Kailun Yang, Rainer Stiefelhagen

Grounded Situation Recognition (GSR) is capable of recognizing and interpreting visual scenes in a contextually intuitive way, yielding salient activities (verbs) and the involved entities (roles) depicted in images.

Tightly-Coupled LiDAR-Visual SLAM Based on Geometric Features for Mobile Agents

no code implementations15 Jul 2023 Ke Cao, Ruiping Liu, Ze Wang, Kunyu Peng, Jiaming Zhang, Junwei Zheng, Zhifeng Teng, Kailun Yang, Rainer Stiefelhagen

On the other hand, the entire line segment detected by the visual subsystem overcomes the limitation of the LiDAR subsystem, which can only perform the local calculation for geometric features.

Attention-based Part Assembly for 3D Volumetric Shape Modeling

no code implementations17 Apr 2023 Chengzhi Wu, Junwei Zheng, Julius Pfrommer, Jürgen Beyerer

Modeling a 3D volumetric shape as an assembly of decomposed shape parts is much more challenging, but semantically more valuable than direct reconstruction from a full shape representation.
