Seminar Announcement


Title: 3D Facial Feature Extraction and Global Motion Recovery using Multi-modal Information
Speaker: Dr Sang-Hoon Kim
  Department of Control and Instrumentation Engineering
Hankyong National University, Korea
Date: Tuesday 26th June, 2001
Time: 12.00pm
Venue: Room 1.24

Abstract:

This seminar presents an automatic a 3D facial feature extraction technique that is used to extract global motion information from a 2D image sequence for the MPEC-4 SNHC face model encoding. The facial regions are detected from the image sequence by using multi-modal fusion technique that combines range, color and motion information. We extract 23 facial features of the MPEG-4 FDP (Face Definition Parameters) inside the facial region using morphological processing. The extracted facial features are used to recover the 3D shape and global motion of the object using the paraperspective factorization method. The recovered 3D motion information is transformed into global motion parameters of FAP (Face Animation Parameters) of the MPEC-4 to synchronize a generic face model with a real face.
