Thesis: Irfan Essa’s PhD Thesis (1994): “Analysis, interpretation and synthesis of facial expressions”

Irfan Essa (1994), “Analysis, interpretation and synthesis of facial expressions“, PhD Thesis, MIT, Cambridge, MA, USA. (Advisor: Alex (Sandy) Pentland) [PDF] Abstract This thesis describes a computer vision system for observing the “action units” of a face using video sequences as input. The visual observation (sensing) is achieved by using an optimal estimation optical flow […]

Paper in IEEE CVPR (1994) on A Vision system for observing and extracting facial action parameters”

Abstract We describe a computer vision system for observing the “action units” of a face using video sequences as input. The visual observation (sensing) is achieved by using an optimal estimation optical flow method coupled with a geometric and a physical (muscle) model describing the facial structure. This modeling results in a time-varying spatial patterning […]
