Summary :

Since recent decade, the development of high quality acquisition devices for medical applications yielded migration of traditional video analysis techniques into medical domain. One of the fondamental probelms in Video analysis is motion estimation. Amongst the approaches which have been developped for this purpose, the robust motion estimators are of special interest. Initiated in the works by Black and Anondan, they are now more and more penetrating in the medical imaging and analysis. In the first part of the talk we will present a robust motion estimator from primary optical flow. Developed on the basis of robust estimator of Tukey, it allows for compensation of global motion in a video sequence.  The coherence of motion parameters allow for segmenting of video sequences for the primary  video summarisation. The results will be demonstrated on endoscopic videos. In the second part of the seminar we will be interested in primarily optical flow estimation on MRI sequences of beating heart. Here the motion compensation will be presented for MRI – guided thermotherapy, where precise motion compensation is needed for correction of temperature maps. Finally, we will give some insights in modelling of visual attention for wearable video acquisition set-ups in the studies of Instrulmental Activities of Daily living  of people with dementia for egocentric scenes interpretation.
