Goal: To contribute to solutions of recognition problems, relevant to the human visual system and to human comfort.  

We have been addressing the following issues: 

Orientation and frequency description of still and video images for general purposes, 
Decompositions based on Gabor filters, 
Dense orientation maps, 
Interpretation and modelling of dense orientation maps via differential operators (e.g. tensors, Lie groups), modelling dense symmetry fields. 

We have been using our results in the following applications: 

Biometric person authentication by audio and video, face recognition, fingerprint recognition
Content based multi-media data base queries 
Unsupervised image segmentation, and texture analysis 

Projects: 

• Biometric Person Authentication: Face, fingerprint, lip movements,  and speech
  
• EU Network of excellence: BIOSECURE
• OCR for modification based scripts: Ethiopian

Past projects
