Mapping changes in very high resolution satellite data: coupling registration, semantic segmentation and change detection

Abstract

Nowadays, several new satellite and micro satellite constellations are providing plenty of low cost very high resolution data which can observe, with high temporal frequency and spatial resolution, extended regions of the earth. This stream of spaceborne information can significantly contribute to several crucial engineering and environmental monitoring problems though the detection and recognition of multitemporal changes. However, although change detection is a heavily studied problem, it is not a trivial one and most existing approaches address it through step by step procedures with semi-automated or automated registration, segmentation and change detection algorithms.To this end, in this thesis we introduced a single framework which combines energy terms for tackling image registration, semantic segmentation and change detection tasks, through data-driven costs regarding the semantic segmentation likelihoods (various classification approaches can be employed), registration metrics ...
