Object as Query: Lifting any 2D Object Detector to 3D Detection

1 code implementation ICCV 2023 Zitian Wang, Zehao Huang, Jiahui Fu, Naiyan Wang, Si Liu

Existing methods mainly establish 3D representations from multi-view images and adopt a dense detection head for object detection, or employ object queries distributed in 3D space to localize objects.

VcT: Visual change Transformer for Remote Sensing Image Change Detection

1 code implementation17 Oct 2023 Bo Jiang, Zitian Wang, Xixi Wang, Ziyan Zhang, Lan Chen, Xiao Wang, Bin Luo

Then, each pixel of feature map is regarded as a graph node and the graph neural network is proposed to model the structured information for coarse change map prediction.

Human-centric Relation Segmentation: Dataset and Solution

no code implementations24 May 2021 Si Liu, Zitian Wang, Yulu Gao, Lejian Ren, Yue Liao, Guanghui Ren, Bo Li, Shuicheng Yan

For the above exemplar case, our HRS task produces results in the form of relation triplets <girl [left hand], hold, book> and exacts segmentation masks of the book, with which the robot can easily accomplish the grabbing task.

Multi-view Human Body Mesh Translator

no code implementations4 Oct 2022 Xiangjian Jiang, Xuecheng Nie, Zitian Wang, Luoqi Liu, Si Liu

Existing methods for human mesh recovery mainly focus on single-view frameworks, but they often fail to produce accurate results due to the ill-posed setup.

Eliminating Cross-modal Conflicts in BEV Space for LiDAR-Camera 3D Object Detection

no code implementations12 Mar 2024 Jiahui Fu, Chen Gao, Zitian Wang, Lirong Yang, Xiaofei Wang, Beipeng Mu, Si Liu

Recent 3D object detectors typically utilize multi-sensor data and unify multi-modal features in the shared bird's-eye view (BEV) representation space.
