Apart from the activities reported in previous sections, we also spend much time and effort on outside contacts. These contacts are aimed at colleagues in academia, at industries based on image analysis or need of it, and at society in general. We participate in conferences; give and organize seminars; receive visitors and make visits, both for long and short stays; and participate in many different committees, both international and national. In the following Section, we have listed these activities for the year 2011. We have left out all meetings within ongoing research projects and all lectures we have given or attended as part of the regular educational activities. Still, the lists are quite extensive.
An important event during the year was the external evaluation of research at UU conducted through the so called KoF11. The international expert panel that evaluated the research at CBA visited us on May 10.
Professor Stefan Seipel has served as Vice-chair of the Swedish Society for Computer Graphics (SIGRAD). Professor Ewert Bengtsson continued to serve as advisor to the Rector of UU on information technology and also as Chair of the UU IT-council, together with many other related appointments. Professor Gunilla Borgefors is Editor in Chief for Pattern Recognition Letters. Professor Ingela Nyström served as Secretary of the International Association of Pattern Recognition (IAPR).
To give some figures: We held as many as 11 seminars outside CBA, mostly in the Uppsala area, but also in The Netherlands, Denmark and USA. We had 15 invited seminars at CBA, from the USA, France, India, Canada and Sweden. In addition, we held 37 seminars in our ``Monday seminar series'', of which nine were Master Thesis presentations. We gave one special invited talks as well as nine oral and four poster presentations at international fully reviewed conferences, and twelve other oral conference presentations. We had long-term visitors from Canada, India and Cote d'Ivoire. In addition, Erik Wernersson paid a long visit to Fachhochschule, Salzburg, and Dept. of Forest and Water Management, Ghent, Belgium; Bettina Selig to the Quantitative Imaging Group at Delft University of Technology and the Eye Hospital Rotterdam, The Netherlands; Amin Allalou Massachusetts Institute of Technology, Cambridge, USA; and Ida-Maria Sintorn BROAD Institute, Boston, USA. We have also had a large number of national and international short-term visitors at many different occasions and have often visited others ourselves. Finally, we have listed 44 international and 43 national ``committees'' of the most varying types in which we have served.
