Algorithm for filtering traffic video images based on mathematical morphology

The application of mathematical morphology in filtering traffic images was discussed with respect to a number of noise sources common in intelligent traffic video images.A noise-filtering algorithm of real traffic video images based on mathematical morphology and frame difference was proposed.Visual C programs for the algorithm were developed and experiments were conducted to test the proposed algorithm.The processing results of different morphologic algorithms for the same set of traffic images were compared.The comparison results show that the proposed algorithm effectively separates and preserves the moving vehicles in the traffic images and achieves good noise filtering results.
