ABSTRACT:
A screen-to-registration surface interface translates coordinate system parameters associated with screen-base image manipulation software to latitude and longitude parameters of a co-registration surface-based coordinate system. By invoking a data file linking mechanism of the `windows`-based display and manipulation software, the user may specify a given image manipulation operation to be executed with respect to plural images that have been imported into respective windows of the display. The registration surface coordinate system parameters are compatible with image collection geometry models. These values are then transformed by the respective collection geometry models to the respective digital image files of the linked images. To display these new pixel values, the geometry models associated with the respective digital images imported to the display screen are mapped by a cascaded mapping function, which cascades the image database-to-registration surface translation of the collection geometry model with the registration surface-to-screen coordinate transform, thereby coupling the new pixel values at the image array locations in the database specified by the manipulation parameters to the output display for exploitation by the user.
