We propose a moving edge extraction using the concept of entropy and cross-entropy, in which the cross-entropy concept is applied to dynamic scene analysis. The cross- entropy concept provides enhancement of detection for the dynamically changed area. We combine the results of cross- entropy in the difference picture (DP) with those of entropy in the current frame so that we can effectively extract moving edges. We also propose the moving edge extraction method by combining the results of cross-entropy and those of Laplacian of Gaussian (LoG).
