Abstract
A novel unsupervised technique for the detection of changes in multitempora l remote sensing images is presented. It adaptively exploits the spatial-co ntextual information contained in the neighbourhood of each pixel to reduce the effects of noise and hence to increase change-detection accuracy. In a ddition, the proposed definition of an adaptive pixel neighbourhood allows a precise location of the borders of changed areas.
