Image Registration

Image RegistrationThe image registration software which works under Windows NT environment, registers images of same geographical location obtained at different time. The software inputs images of two different dates with different spatial and spectral resolutions. It allows interactive selection of registration control points (RCPs) efficiently using zoom window. The image in the zoom window can be enhanced to enable the operator to accurately select the feature. The software also allows to refine the RCPs by displaying root mean square errors in a separate window. The control point with error more than 0.99 can be reselected.
