Point Mapping

The Image Processing Toolbox provides tools to support point mapping to determine the parameters of the transformation required to bring an image into alignment with another image. In point mapping, you pick points in a pair of images that identify the same feature or landmark in the images. Then, a spatial mapping is inferred from the positions of these control points.

The following figure provides a graphic illustration of this process. This process is best understood by looking at an example. See Example: Registering to a Digital Orthophoto for an extended example.
