||This monday seminar is going to deal with image filtering from four different perspectives and for four different reasons. First of all, filtering for object tracking/segmentation by the mean shift approach. Secondly, a short discussion about sampling rates in density estimations. The third topic is a suggestion for a crude preprocessing ("image simplication") by "global" thresholding using spline approximation. And finally, a very short introduction to a Baysian approach to image denoising.
