I am mainly interested in both theory and applications of object recognition. Currently, most of my time is spent on the problems of colour-based image retrieval, face verification and on recognition using invariant pixel sets. In the last couple of years I have published on colour-based recognition and segmentation, face authentication, Hough Transform, lip tracking, active vision , combination of evidence and other topics not so easily classified (clearly I need more focus!). The complete list of publications has about 90 items.
