With each new Earth or Space Science mission, the volume of acquired data and its diversity significantly increase. Remote sensing data are being collected over the same areas with multiple resolutions - temporal, spatial, and radiometric - as well as with different viewpoints. One of the first requirements in the integration and the analysis of such large amounts of diverse data is Image Registration, i.e., the precise pixel-to-pixel alignment of two different images or the alignment of one image to a map. In particular, accurate registration is essential for creating mosaics of satellite images or for tracking changes on a planet's surface over time; for example, in Earth Science, change detection over time or scale is only possible if multisensor and multitemporal data are accurately calibrated through registration. In planetary exploration, the exact localization of potential features, such as hazards and resources, is required for successful precision landing and for accurate planet exploration. After giving a definition and the motivations for doing image registration, this talk will provide a brief overview of the state-of-the-art, both from a theoretical point of view and from operational satellite systems, and will then describe some of the recent work performed at Goddard in that area.

Dr. Jacqueline Le Moigne is the Assistant Chief for Technology in the Software Engineering Division at NASA Goddard. She is also Goddard Center Associate for the Earth Science Technology Office (ESTO) Advanced Information Systems Technology (AIST) Program. During her 22 years experience at NASA, Dr. Le Moigne has performed extensive work in the analysis of remote sensing data, particularly image registration, high-performance and on-board processing. She holds a Ph.D. in Computer Science from the University Pierre and Marie Curie, France. She has published over 100 publications, and has co-edited a book on "Image Registration for Remote Sensing" published by Cambridge University Press in 2011. She regularly serves as a member of technical conference committees and as a reviewer for various international journals. She has been an Associate Editor for the IEEE Transactions on Geoscience and Remote Sensing as well as for the Journal Pattern Recognition. She is a NASA Goddard Senior Fellow, an IEEE Senior Member and a Program Evaluator for the Accreditation Board in Engineering and Technology (ABET). She was a NATO Science for Peace and Security Committee Panel Member from 2008 to 2011. In 2012, she received the Goddard Information Science & Technology (IS&T) Award and the NASA Exceptional Service Medal.
