General background

The Centre for Image Analysis (CBA) carries out research and graduate education in computerized image analysis and perceptualization. Our work ranges from the purely theoretical to methods, algorithms and systems for applications primarily in biomedicine and forestry.

CBA is collaboration between Uppsala University (UU) and the Swedish University of Agricultural Sciences (SLU) which started in 1988. Through this year we have been a single administrative unit with our administration carried out at UU but with employees at both universities. Our finances came in three roughly equal parts from the two universities and external grants, or more precisely 35% from UU, 25% from SLU and 40% grants for a total budget of about 20 MSEK.

During 2010 our two host universities decided to change our organization and from the beginning of 2011 we are two separate administrative units, one at each university. At UU we are a division within the Dept. of Information Technology and at SLU a yet to be defined entity. Our hosts have explicitly stated that this reorganization will not change our identity as a single research center, so we hope to continue our very close collaboration also in the future.

During 2010, a total of 39 persons have been working at CBA: 19 researchers, 18 PhD students and one administrator. Additionally, 12 Master thesis students have finished their thesis work with supervision from CBA. This does not mean, however, that we have had 51 full-time persons at CBA; many have split appointments, part time at CBA and part time elsewhere, most commonly at the Dept. of Information Technology. Some of our senior researchers have their main work place elsewhere but are retaining a small part time position at CBA mainly in order to supervise their PhD students until graduation. Last year CBA had about 23 full-time employees, not counting undergraduate teaching and Master thesis students. Most of us at CBA also pursue some undergraduate teaching that is organized by the Dept. of Information Technology at UU.

On average three-four PhD dissertations are produced each year. In 2010 two PhD theses were defended: Magnus Gedda at UU and Kristin Norell at SLU. This year Gunilla Borgefors served as conferrer at the traditional conferment ceremony at SLU when the new doctors receive their laurels, a once-in-a-lifetime honor.

Maria Axelsson received the Benzelius award from the Royal Society of Sciences in Uppsala for her PhD thesis. We were also pleased that two of our former PhD students, Anders Hast and Pasha Razifar, qualified as docents, bringing the total number of CBA docents to nine.

Image processing is highly interdisciplinary, with foundations in mathematics, statistics, physics, signal processing and computer science, and with applications in many diverse fields. We are working in a wide range of application areas, most of them related to life sciences and usually in close collaboration with domain experts. Our collaborators are found locally as well as nationally and internationally. For a complete list of our 46 national and 42 international collaborators see Section [*]. One of our collaborating groups, Uppsala Multidisciplinary Center for Advanced Computational Science (UPPMAX), is located on our premises and is managed by Ingela Nyström and administrated by Lena Wadelius.

In theoretical research, we focus on discrete geometry and multi-dimensional images, in both the spatial and spectral domains. Over the last several years we have expanded our activities in perceptualization. During 2009 we started a new major project in this area, under leadership of visiting Professor Ingrid Carlbom, with the goal of creating an augmented reality system in which you can see, feel, and manipulate virtual 3D objects as if they were real using a haptic glove. This project has progressed very well during 2010 and we now have a first working prototype, albeit still with limited functionality. Our studio 3DIS4U, 3D Image Studio for Uppsala, is used for our seminars, some classes, and for external events. Our current projects are visualized on our ``CBA TV'', in the form of very short ``trailers'' on a LCD monitor facing the main entrance stairway where students and colleagues from other groups can get a glimpse of our most current research.

We organized the national Swedish conference on image analysis, SSBA in March with 100 participants and we were also involved in the organization of seven other conferences, ranging from area co-chairing the world conference ICPR to hosting collaborative workshops with our international partners.

We are very active in international and national societies. Ingela Nyström served as second vice-president of the International Association of Pattern Recognition (IAPR) and was in September elected secretary of IAPR. Gunilla Borgefors was Area Editor for Pattern Recognition Letters and is now appointed Editor in Chief. Researchers at CBA also served on several other journal editorial boards, scientific organization boards, and conference committees. We were involved in half a dozen PhD dissertation committees, nationally and internationally. And we took a very active part in reviewing grant applications and scientific papers submitted to conferences and journals. Ewert Bengtsson served as chair of the Evaluation Panel for Medical Engineering for the Swedish Research Council and on a panel for evaluating advanced research proposals for the European Research Council. Locally he serves as senior advisor to the Rector of UU on information technology and also as Chair of the University IT-council, and holds many other related appointments.

Since 1993/94, CBA assembles extensive annual reports, such as this document, that describes in some detail what we achieved during the year. These annual reports are intended for anyone interested in our work. Note that each section in this report starts with a short summary printed in a larger font than the following detailed material.

Our annual reports have been available on the Internet since 1998. For this issue, see
