Social-MAE: Social Masked Autoencoder for Multi-person Motion Representation Learning

no code implementations8 Apr 2024 Mahsa Ehsanpour, Ian Reid, Hamid Rezatofighi

The framework uses masked modeling to pre-train the encoder to reconstruct masked human joint trajectories, enabling it to learn generalizable and data efficient representations of motion in human crowded scenes.

JRDB-Act: A Large-scale Dataset for Spatio-temporal Action, Social Group and Activity Detection

no code implementations CVPR 2022 Mahsa Ehsanpour, Fatemeh Saleh, Silvio Savarese, Ian Reid, Hamid Rezatofighi

However, learning to recognise human actions and their social interactions in an unconstrained real-world environment comprising numerous people, with potentially highly unbalanced and long-tailed distributed action labels from a stream of sensory data captured from a mobile robot platform remains a significant challenge, not least owing to the lack of a reflective large-scale dataset.

Joint Learning of Social Groups, Individuals Action and Sub-group Activities in Videos

no code implementations ECCV 2020 Mahsa Ehsanpour, Alireza Abedin, Fatemeh Saleh, Javen Shi, Ian Reid, Hamid Rezatofighi

In this paper, we solve the problem of simultaneously grouping people by their social interactions, predicting their individual actions and the social activity of each social group, which we call the social task.
