Geometric Transformation and Image Registration

Scale, rotate, perform other N-D transformations, and align images using intensity correlation, feature matching, or control point mapping

The toolbox supports functions to perform simple geometric transformations, such as resizing, rotating, and cropping, as well as more complex affine and projective geometric transformations. The toolbox also provides tools for aligning a pair of images automatically using intensity correlation, feature matching, or control point mapping techniques.

The value of a transformed point in the output coordinate space is determined by mapping to the corresponding point in the input coordinate space.
