Abstract:

An effective built-up areas extraction algorithm of high-resolution remote sensing images is proposed in this paper. Based on a signal processing method, we present a texture description method for the characteristics of built-up areas in high-resolution remote sensing images. Through an information theory based visual attention mechanism, a saliency map is calculated to extract built-up areas. Experiments prove the effectiveness of the proposed algorithm.

Key words: high-resolution remote sensing images, NSCT, textural features, visual saliency, built-up areas extraction
