RSPNet: Relative Speed Perception for Unsupervised Video Representation Learning

AAAI 2021technical

We study unsupervised video representation learning that seeks to learn both motion and appearance features from unlabeled video only, which can be reused for downstream tasks such as action recognition. This task, however, is extremely challenging due to 1) the highly complex spatial-temporal infor…

Graph-PCNN: Two Stage Human Pose Estimation with Graph Pose Refinement

ECCV 2020poster

Recently, most of the state-of-the-art human pose estimation methods are based on heatmap regression. The final coordinates of keypoints are obtained by decoding heatmap directly. In this paper, we aim to find a better approach to get more accurate localization results. We mainly put forward two sug…

Attention Clusters: Purely Attention Based Local Feature Integration for Video Classification

CVPR 2018poster

Recently, substantial research effort has focused on how to apply CNNs or RNNs to better capture temporal patterns in videos, so as to improve the accuracy of video classification. In this paper, however, we show that temporal information, especially longer-term patterns, may not be necessary to ach…
