With interactive registration the user can evaluate the registration accuracy and interactively revise the result. Landmark selection and
correspondence are achieved interactively with limited help from the computer. For instance, the user selects corresponding landmarks
in the images with the mouse and asks the computer to refine the correspondences via template matching. The user then reviews the
refined correspondences, and removes the inaccurate ones. After finding a transformation function from the correspondences and
superimposing the images, if the registration is found not sufficiently accurate, further landmarks are selected and the process is
repeated until desired registration accuracy is reached. Normally, sufficient accuracy can be achieved within a few iterations.
An example of interactive image registration is given below. The top row depicts two images of a terrain scene from up close. Initially,
the user may select a few corresponding landmarks in the images with the mouse (second row) and register the images as depicted in
third row. The user can further select corresponding landmarks in areas that are thought to be inaccurate (fourth row) and repeat the
process to improve the registration (bottom row).
