Fuzzy Segmentation of Color Video Shots

摘要

Fuzzy segmentation is a region growing technique that assigns a grade of membership to an object to each element in an image. In this paper we present a method for segmenting video shots by using a fast implementation of the fuzzy segmentation technique. The video shot is treated as a three-dimensional volume with different z slices being occupied by different frames of the video shot. The volume is interactively segmented based on selected seed elements, that will determine the affinity functions based on their intensity and color properties. Experiments with a synthetic video under different noise conditions are performed, as well as examples of two real video shot segmentations are presented, showing the applicability of our method.
