An effort is underway to develop an automated image registration system for the Landsat-D Ground Segment. This system will be capable of providing accurate control point (CP) location errors in imagery that has been corrected using system models. A part of this effort consisted of studying various image enhancement techniques, correlation techniques and subpixel registration methods. Presented here is an overview of the registration system developed, along with the study results that led to the choices of techniques incorporated.
Although much previous work exists in this area, it is believed that some of the methods and findings are new. It is also hoped that the extensive testing results along with the constraints of a very high speed production environment will be of value to the remote sensing community.
