Abstract :
In this paper, we propose a level-set based method to identify urban areas using multitemporal Synthetic Aperture Radar (SAR) data. Our method is compared to the standard method, called the Otsu´s threshold-based method. The experimental results indicate significant improvement in terms of the Kappa coefficients and the percentage of correctly classified pixels.
