Thermal infrared imagery informativity enhancement using sub-pixel co-registration

Abstract

Spatial resolution is the main specification of satellite imagery quality, including the thermal infrared imagery. Many technical restrictions opposed to realize the high spatial resolution imagers of thermal infrared band. The software-based method for imagery spatial resolution enhancement is presented. The method used two sub-pixel shifted images that contain time-invariant thermal emissivity data. Enhanced spatial resolution infrared imagery provides better informativity for remote sensing application and allow producing more detailed data products based on thermal infrared imagery processing.
