Remote Sensing Image Representation based on Hierarchical Histogram Propagation

Abstract : Many methods have been recently proposed to deal with the large amount of data provided by high- resolution remote sensing technologies. Several of these methods rely on the use of image segmentation algorithms for delineating target objects. However, a common issue in geographic object-based applications is the definition of the appropriate data representation scale, a problem that can be addressed by exploiting multiscale segmentation. The use of multiple scales, however, raises new challenges related to the definition of effective and efficient mechanisms for extracting features. In this paper, we address the problem of extracting histogram-based features from a hierarchy of regions for multiscale classification. The strategy, called H-Propagation, exploits the existing relation- ships among regions in a hierarchy to iteratively prop- agate features along multiple scales. The proposed method speeds up the feature extraction process and yields good results when compared with global low- level extraction approaches.
