Long-term Human Participation Assessment In Collaborative Learning Environments Using Dynamic Scene Analysis

no code implementations14 Apr 2024 Wenjing Shi, Phuong Tran, Sylvia Celedón-Pattichis, Marios S. Pattichis

The proposed dynamic participant tracking system is shown to perform exceptionally well, missing a student in just one out of 35 testing videos.

Talking Detection In Collaborative Learning Environments

no code implementations14 Oct 2021 Wenjing Shi, Marios S. Pattichis, Sylvia Celedón-Pattichis, Carlos LópezLeiva

Our approach uses head detection and projections of the log-magnitude of optical flow vectors to reduce the problem to a simple classification of small projection images without the need for training complex, 3-D activity classification systems.
