Patent ID: 8768018

Claim:
An information processing apparatus including a central processing unit (CPU) comprising: an image acquisition unit configured to acquire a first image of a target object under a first imaging condition; a model generation unit configured to generate, based on the first image, a deformation model of a first shape of the target object under a plurality of deformation conditions, the deformation model representing a plurality of deformed shapes of the target object in which a position of a feature region in each of the deformed shapes coincides with each other; a deformation estimation unit configured to calculate an estimated deformation value of the deformation model of first shape under a second imaging condition which is different from the first imaging condition; a displacement vector calculation unit configured to calculate a displacement vector for displacing the first shape in accordance with the estimated deformation value; and a deformation image generation unit configured to, based on the displacement vector, deform the first image to generate a deformed image which corresponds to a second shape of the target object, wherein the deformation estimation unit calculates the estimated deformation value such that the position of the feature region represented by the deformation model and a position of the feature region in the second shape agree with each other, and wherein the CPU controls an operation of at least one of the image acquisition unit, the model generation unit, the deformation estimation unit, the displacement vector calculation unit and the deformation image generation unit.
