An image registration software developed by Image Registration and Fusion Systems enables the user to quickly translate,
rotate, and scale one image with respect to another while viewing the result. A clearly visible landmark is taken in both images
as the anchor point about which rotation and scaling is performed. The process is demonstrated below. The top left shows a
Landsat 7 image of the Tokyo Bay area. The anchor point is marked with a '+' in top right image. Scaling and rotation will be
with respect to the anchor point. The second image is an ASTER image of the same area (middle left). The ASTER image is
translated so the selected landmark coincides with the '+' (middle right) and then rotated and scaled with respect to the
Landsat image with the motion of the mouse to align the images (bottom left). The images can be viewed in their original
intensities, or the intensity of one image can be inverted to emphasize misregistered areas (bottom right). A typical registration
by this software takes a few minutes of interaction by the user.
This manual image registration software is limited to images with translational, rotational, and scaling differences. Images
taken from about the same view-angle of a scene can be registered with this software. The software can read and save
images in a variety of formats. It also has the ability to zoom in an area and facilitate evaluation of the registration quality.
