A hierarchical approach to automated registration of high resolution satellite imagery for change detection

Abstract

GIS databases need to undergo frequent updating due to rapid changes in the physical environment. Satellite imagery, with its recently enhanced spatial, spectral and temporal resolution, allows for accurate and reliable detection and characterization of patterns of change. A key factor that dictates the validity and reliability of change detection results is the quality of image registration. There is a need to develop robust registration procedures for multi-temporal, multi-spectral and/or multi-resolution imagery captured from different sensors to facilitate the change detection process. This paper discusses an approach for automated image registration based on a hierarchical image matchin..
