Bilingual Speech Recognition by Estimating Speaker Geometry from Video Data
Luis Sanchez Tapia, Antonio Gomez, Mario Esparza +4
Speech recognition is very challenging in student learning environments that are characterized by significant cross-talk and background noise. To address this problem, we present a…
Person Detection in Collaborative Group Learning Environments Using Multiple Representations
Wenjing Shi, Marios S. Pattichis, Sylvia Celedón-Pattichis +1
We introduce the problem of detecting a group of students from classroom videos. The problem requires the detection of students from different angles and the separation of the grou…
Facial Recognition in Collaborative Learning Videos
Phuong Tran, Marios Pattichis, Sylvia Celedón-Pattichis +1
Face recognition in collaborative learning videos presents many challenges. In collaborative learning videos, students sit around a typical table at different positions to the reco…
Talking Detection In Collaborative Learning Environments
Wenjing Shi, Marios S. Pattichis, Sylvia Celedón-Pattichis +1
We study the problem of detecting talking activities in collaborative learning videos. Our approach uses head detection and projections of the log-magnitude of optical flow vectors…
Fast Hand Detection in Collaborative Learning Environments
Sravani Teeparthi, Venkatesh Jatla, Marios S. Pattichis +2
Long-term object detection requires the integration of frame-based results over several seconds. For non-deformable objects, long-term detection is often addressed using object det…
