CLUSTSEG: Clustering for Universal Segmentation

1 code implementation3 May 2023 James Liang, Tianfei Zhou, Dongfang Liu, Wenguan Wang

We present CLUSTSEG, a general, transformer-based framework that tackles different image segmentation tasks (i. e., superpixel, semantic, instance, and panoptic) through a unified neural clustering scheme.

Fusion is Not Enough: Single Modal Attacks on Fusion Models for 3D Object Detection

no code implementations28 Apr 2023 Zhiyuan Cheng, Hongjun Choi, James Liang, Shiwei Feng, Guanhong Tao, Dongfang Liu, Michael Zuzak, Xiangyu Zhang

We argue that the weakest link of fusion models depends on their most vulnerable modality, and propose an attack framework that targets advanced camera-LiDAR fusion-based 3D object detection models through camera-only adversarial attacks.

Learning Equivariant Segmentation with Instance-Unique Querying

1 code implementation3 Oct 2022 Wenguan Wang, James Liang, Dongfang Liu

Prevalent state-of-the-art instance segmentation methods fall into a query-based scheme, in which instance masks are derived by querying the image feature using a set of instance-aware embeddings.

Physical Attack on Monocular Depth Estimation with Optimal Adversarial Patches

1 code implementation11 Jul 2022 Zhiyuan Cheng, James Liang, Hongjun Choi, Guanhong Tao, Zhiwen Cao, Dongfang Liu, Xiangyu Zhang

Experimental results show that our method can generate stealthy, effective, and robust adversarial patches for different target objects and models and achieves more than 6 meters mean depth estimation error and 93% attack success rate (ASR) in object detection with a patch of 1/9 of the vehicle's rear area.
