A 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 registration. 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 center of the window is marked with a '+'. Scaling and rotation will be with respect to the window center. A clear
landmark is identified and the image is translated interactively by dragging the mouse so that the landmark coincides with the '+' (top
right). The second image is an ASTER image of the same area (middle left). The ASTER image is also 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 approximately one minute.
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.
