The paper presents an information theory approach for change detection, using Earth observation images. Correlation coefficient and Kullback-Leibler divergence are used as similarity measures allowing to find out where did change occur. Further, for an image characterization method, rate distortion theory is implemented to delimitate image complex regions,(More)
In natural hazards management applications Earth Observation (EO) image processing methods are based on segmentation and classification. The result primary consists of thematic maps which are readily interpretable. We propose a complete EO image processing chain, which generates an end product with increased information content organized in thematic layers.(More)
Nowadays the earth observation sensors provide images containing detailed information relevant for applications related to hazard or security matters. Unfortunately, image information mining, its interpretation and transformation in products useful to the rescue or decision teams is still a laborious task, effectuated many times by visual inspection and(More)
