Multi-dimensional (MD) filters can be used for processing spatio-temporal signals which appear in many applications such as broadband beamforming, video, light field processing etc. Light field images consist of a 2-D array of images while light field videos consist of a 2D array of videos.  Light field videos make the enhancement of moving objects depending on their depth and velocity possible.  Recently depth-velocity filters have been developed for this task and are shown to provide better performance than conventional 3-D video or 4-D light field processing. In this talk recent developments in the design of MD filters for processing of light field videos will be presented.

Biography:

Pan Agathoklis received the Dipl. Ing. Degree in electrical engineering and the Dr. Sc. Techn. Degree from the Swiss Federal Institute of Technology, Zurich, Switzerland.  Since 1983, he has been with the Department of Electrical and Computer Engineering, University of Victoria, B.C., Canada, where he is currently a Professor.

His fields of interest are in multidimensional digital signal processing, control, and their applications. He has worked in the developing new techniques for evaluating stability and performance of MD systems and these techniques have been used for broadband beamforming applications in radio astronomy and communications. He has developed methods for reconstruction of images and video from gradient data and applied these results in adaptive optics and in editing of images and video applications.
