          Automatic Image Registration of Remotely Sensed Data

	The study of global environmental changes involves the comparison,
fusion, and integration of multiple types of remotely-sensed data at
various temporal, radiometric, and spatial resolutions. Results of this
integration may be utilized for global change analysis, as well as for the
validation of new instruments or for new data analysis. Furthermore,
smaller missions will include many different sensors carried on separate
platforms, and the amount of remote sensing data to be combined will
increase tremendously. For all of these applications, the first required
step is fast and automatic image registration.

	As this need for automating registration techniques is being
recognized, it becomes necessary to survey all the registration methods
which may be applicable to Earth and space science problems and to evaluate
their performances on a large variety of existing remote sensing data as
well as on simulated data of soon-to-be-flown instruments. In this talk,
the image registration concept will be introduced, different techniques
will be reviewed, and the first steps toward an exhaustive quantitative
evaluation will be described.
