Dynamic Color Lines

This paper proposes a new color model of videos, Dynamic Color Lines, as an extension of Color Lines Model for images. With our model, videos are assumed to be represented as dynamically moving elongated clusters in a 3-D RGB space. This can be done by assigning each pixel to the nearest cluster and by updating cluster directions and locations alternatively. The dynamic color lines model provides a heuristic approach for a new sparse and robust representation of videos. In numerical experiments, segmentation of surveillance videos and compression are performed.
