Abstract
Image registration is the process of overlaying two or more images of the same scene taken at different times, from different viewpoints, and/or by different sensors. Registration is among the most fundamental operations to generate almost all data products from remotely sensed scenes. It is a challenging task due to inevitable geometric and radiometric distortions during the data acquisition process. The presence of clouds makes the problem even more complicated. This article presents the development of operational software for multitemporal and multiband image registration for KALPANA-1 and INSAT-3A at the Indian Space Research Organization (ISRO).
