1. An information processing apparatus for executing a process for deforming a shape of an original image so as to approximate a shape of a target image, comprising: an obtaining unit configured to obtain a deformation rule by associating a movement of a feature area caused by deformation of the original image with the deformation; and a deformation unit configured to deform the original image in accordance with the deformation rule, using, as a condition of constraint, position information about a feature area of the target image and a corresponding area of the original image.
