A conceptual framework for change detection in very high resolution remote sensing images

This paper addresses the problem of change detection (CD) in very high geometrical resolution (VHR) multitemporal images. In this context, we propose a general conceptual framework that aims at giving: i) a taxonomy of different radiometric changes occurring when dealing with VHR remote sensing images; and ii) a global approach to the definition of the architecture of effective CD methods for VHR images. This framework represents a first step for defining effective guidelines for the development of a new generation of CD methods that can be properly analyze multitemporal VHR images taking into account the intrinsic complexity associated with these data.
