Alexander Toet

senior scientist
Soesterberg, The Netherlands
Alexander Toet received his PhD in physics from the University of Utrecht in the Netherlands in 1987, where he worked on visual spatial localization (hyperacuity) and image processing. His is currently a senior research scientist at TNO (Soesterberg, The Netherlands) where he investigates multimodal image fusion, image quality, computational models of human visual search and detection, and the quantification of visual target distinctness. He also investigates crossmodal perceptual interactions between the visual, auditory, olfactory and tactile senses, with the aim to deploy these interactions to tune the perceived affective quality of both virtual and real environments. He is currently affiliated with the Faculty of Social and Behavioral Sciences of the University of Utrecht where he researches the perception of multimodal imagery and the emotional bias induced by affective visual backgrounds. He has published over 70 papers in refereed journals, 80 papers in refereed conference proceedings, was co-editor of a book on the mathematical description of shape in images, was Guest Editor of Special Issue of Optical Engineering on “Advances in Target Acquisition Modeling II”, and is currently Area Editor of the ISIF Journal of Advances in Information Fusion. He organized and directed 3 international workshops on Search and Target Acquisition, Combinatorial algorithms for Military Applications, and on the mathematical description of shape in images. He is also Fellow of The International Society for Optical Engineering (SPIE) and Senior Member of The Institute of Electrical & Electronics Engineers (IEEE).
