The perception, interpretation and presentation of our environment using sensors and computer technology, in combination with related communication and visualization techniques, present research challenges of high importance and growing impact for our society. Related applications include automation tasks such as household robots or the autonomous navigation of wheelchairs, the huge multimedia market with innovations on the TV and mobile phone sectors (e.g., personalized/interactive video or TV), surveillance and security tasks, or the automated generation of 3D city models or virtual worlds from remote sensing data, to name just a few of them.

The proposed doctoral college “Computational Perception” is intended to work on such problems by bringing together experts in the field of geoinformation/photogrammetry (precise measurements from images delivered by different types of cameras), in the field of computer science (image processing and computer graphics, algorithms and efficient implementation) as well as electrical engineering (object and scene perception, sensors and displays) and telecommunication (multi-sensor coding, optimal data transmission, video quality), thus addressing such hot research topic with a multi-faculty approach. Figure 1 illustrates the complementary background and expertise of the three participating departments within the joint doctoral college.

Some informal collaboration between the partners started already in 2006, when the benefits of a joint approach were recognized during the VIDIMGRAPH (Video, Image Processing and Computer Graphics) workshop, which was stimulated and organized by Prof. Markus Rupp. During that workshop, researchers from three departments met to present their work, exchange ideas, and to identify potential synergisms between the different groups at TU Vienna. This workshop can be seen as a starting point of our inter-department collaboration, which we would like to intensify and further develop in a formalized way under the proposed doctoral college “Computational Perception”.
