Contrastive Boundary Learning for Point Cloud Segmentation
Liyao Tang, Yibing Zhan, Zhe Chen +2
Point cloud segmentation is fundamental in understanding 3D environments. However, current 3D point cloud segmentation methods usually perform poorly on scene boundaries, which deg…
SASA: Semantics-Augmented Set Abstraction for Point-based 3D Object Detection
Chen Chen, Zhe Chen, Jing Zhang +1
Although point-based networks are demonstrated to be accurate for 3D point cloud modeling, they are still falling behind their voxel-based competitors in 3D detection. We observe t…
Expression Snippet Transformer for Robust Video-based Facial Expression Recognition
Yuanyuan Liu, Wenbin Wang, Chuanxu Feng +3
The recent success of Transformer has provided a new direction to various visual understanding tasks, including video-based facial expression recognition (FER). By modeling visual…
Dynamic Attention guided Multi-Trajectory Analysis for Single Object Tracking
Xiao Wang, Zhe Chen, Jin Tang +4
Most of the existing single object trackers track the target in a unitary local search window, making them particularly vulnerable to challenging factors such as heavy occlusions a…
Recent Progress in Appearance-based Action Recognition
Jack Humphreys, Zhe Chen, Dacheng Tao
Action recognition, which is formulated as a task to identify various human actions in a video, has attracted increasing interest from computer vision researchers due to its import…
Condensing Two-stage Detection with Automatic Object Key Part Discovery
Zhe Chen, Jing Zhang, Dacheng Tao
Modern two-stage object detectors generally require excessively large models for their detection heads to achieve high accuracy. To address this problem, we propose that the model…
