Abstract

Change detection (CD) for remotely sensed images has gained great relevance in the last decade due to an increase in the number of Earth Observation (EO) missions, improved temporal resolutions, and open data policies. However, efficient exploitation and integration of spatial information for CD remain challenging issues. This paper proposes a multiscale superpixel segmentation based band expansion approachto address these issues. Superpixels derived at different scales are used to extract spatial information of objects and landscapes of various sizes, and this information is integrated in the form of new spectral bands. The expanded band set may then be used with any CD method, whether for binary or multi-class CD. Experimental results on multispectral (MS) and hyperspectral (HS) multitemporal images validate the proposed approach’s performance benefit.
