We present a method for motion-based video segmentation and segment classification as a step towards video summarization. The sequential segmentation of the video is performed by detecting changes in the dominant image motion, assumed to be related to camera motion and represented by a 2D affine model. The detection is achieved by analysing the temporal variations of some coefficients of the 2D affine model (robustly) estimated. The obtained video segments supply reasonable temporal units to bedoi:10.1007/s11042-005-0891-0 fatcat:olyw45rdard7tjbuayqfbm6oym
