computer vision, gesture recognition, human-computer interaction, and medical applications

• Biomedical Image Analysis - We are an interdisciplinary team interested in develping algorithms for biomedical image analysis under an image feature-based machine learning framework.
• Computational Symmetry - We are develping techniques for applying computational symmetry (symmetry detection, representation, and reasoning) in computer vision, graphics and robotics.
• Face Group - Robust detection, recognition, and tracking of human faces with automated analysis of expressions
• Human Identification at a Distance - We are developing and evaluating human identification technologies as part of the Defense Advanced Research Projects Agency (DARPA) sponsored program in Human Identification at a Distance (HumanID).

• 3D Head Motion Recovery in Real Time - A cylindrical model-based algorithm recovers the full motion (3D rotations and 3D translations) of the head in real time.
• Cohn-Kanade AU-Coded Facial Expression Database - An AU-coded database of over 2000 video sequences of over 200 subjects displaying various facial expressions.
• Deception Detection - Learning facial indicators of deception
• Depression Assessment - This project aims to compute quantitative behavioral measures related to depression severity from facial expression, body gestures, and vocal prosody in clinical interviews.
• Facial Asymmetry as a Biometric - We are investigating the effect of facial asymmetry measurement statistics as a biometric under expression variations.
• Facial Expression Analysis - Automatic facial expression encoding, extraction and recognition, and expression intensity estimation for the applications of MPEG4 application: teleconferencing, human-computer interaction/interface.
• Quality of Life Technology Center - QoLT is a unique partnership between Carnegie Mellon and the University of Pittsburgh that brings together a cross-disciplinary team of technologists, clinicians, industry partners, end users, and other stakeholders to create revolutionary technologies that will improve and sustain the quality of life for all people.
• Spatio-Temporal Facial Expression Segmentation - A two-step approach temporally segment facial gestures from video sequences. It can register the rigid and non-rigid motion of the face.
