Abstract:Bandwidths and weights of sampling points are two key points in mean shift based image smoothing and segmentation. Bandwidths indicate spatial bandwidths and range bandwidths. Adaptive spatial bandwidths are defined according to color distribution of the image. Then, adaptive range bandwidths are obtained by minimizing the local variance function and maximizing the frequency structural similarity function. Additionally, weights of sampling points are defined to overcome over smoothness. Experimental results prove that the correct segmented regions are obtained by using the proposed bandwidths and weights. Copyright ? 2010 Acta Automatica Sinica. All rights reserved.
