PKF: Probabilistic Data Association Kalman Filter for Multi-Object Tracking

1 code implementation10 Nov 2024 Hanwen Cao, George J. Pappas, Nikolay Atanasov

We view the unknown data association as a latent variable and apply Expectation Maximization (EM) to obtain a filter with update step in the same form as the Kalman filter but with expanded measurement vector of all potential associations.

SuctionNet-1Billion: A Large-Scale Benchmark for Suction Grasping

no code implementations23 Mar 2021 Hanwen Cao, Hao-Shu Fang, Wenhai Liu, Cewu Lu

Meanwhile, we propose a method to predict numerous suction poses from an RGB-D image of a cluttered scene and demonstrate our superiority against several previous methods.

TDAF: Top-Down Attention Framework for Vision Tasks

no code implementations14 Dec 2020 Bo Pang, Yizhuo Li, Jiefeng Li, Muchen Li, Hanwen Cao, Cewu Lu

Such spatial and attention features are nested deeply, therefore, the proposed framework works in a mixed top-down and bottom-up manner.

ASAP-Net: Attention and Structure Aware Point Cloud Sequence Segmentation

1 code implementation12 Aug 2020 Hanwen Cao, Yongyi Lu, Cewu Lu, Bo Pang, Gongshen Liu, Alan Yuille

In this paper, we further improve spatio-temporal point cloud feature learning with a flexible module called ASAP considering both attention and structure information across frames, which we find as two important factors for successful segmentation in dynamic point clouds.

Deep RNN Framework for Visual Sequential Applications

1 code implementation CVPR 2019 Bo Pang, Kaiwen Zha, Hanwen Cao, Chen Shi, Cewu Lu

There are mainly two novel designs in our deep RNN framework: one is a new RNN module called Context Bridge Module (CBM) which splits the information flowing along the sequence (temporal direction) and along depth (spatial representation direction), making it easier to train when building deep by balancing these two directions; the other is the Overlap Coherence Training Scheme that reduces the training complexity for long visual sequential tasks on account of the limitation of computing resources.
