• Book Advances in Face Image Analysis: Techniques and Technologies, Y. Zhang (eds.).( IGI Global)
Research interests:
• Segmentation
and analysis of facial features,
• Analysis and recognition of facial expressions,
• Analysis
and recognition of vocal expressions,
• Context-sensitive facial expression recognition (Pain monitoring),
• Data
fusion by the Transferable Belief Model,

• Data
fusion.
Database:
Hammal-Caplier database: 21 different subjects with 3 sequences per subject (Smile, Surprise and Disgust). Each sequence is recorded during 5 seconds. For each different acquisition the subject is asked to simulate one expression beginning by the Neutral expression, evolving to the considered expression and coming back to the Neutral expression.
