Aerospace Instrument-Making Annotation << Back Algorithm for Automatic Change Detection in Satellite Images With Data Integration in a Geoinformation System Lokhvitskiy V.A., Yakovlev E.L., Bushev I.V. An algorithm for automatic change detection in satellite imagery is presented, including preprocessing, image comparison, binarization, and contour analysis, followed by georeferencing and vector layer generation. The developed algorithm is integrated into a software package that supports visualization and export of results to geographic information systems (GIS). The effectiveness of the method is demonstrated through real-world satellite image analysis. Keywords: satellite imagery, automatic change detection, geographic information systems, binarization, contour analysis. DOI: 10.25791/aviakosmos.5.2026.1558 Pp. 39-48.
