Change Detection

Change detection algorithms analyze multiple images of the same scene – taken at different times – to identify regions of change. The ability to detect regions of change in images is a powerful tool that can be used in a diverse range of applications including military surveillance, environmental baseline monitoring, land use change analysis, crop stress detection, assessment of deforestation, disaster management (e.g., monitoring of changes during flooding), ice monitoring, medical diagnosis and treatment, and urban planning. AUG Signals has developed several advanced change detection algorithms that may be applied to multiple applications.
