4. Geometric image transformation
The geometric transformation of an image requires the choice of a deformation model to which a certain number of constraints can be applied. In this section, we present various deformation models and the constraints that can be applied to them. We then look at a number of problems relating to image deformation, especially in view of their discrete nature.
4.1 Deformation models
The choice of deformation model is very important and is guided by the underlying application and the a priori information available on the nature of the transformation between images. Among the various deformation models proposed in the literature, we distinguish between linear models (i.e., that can be expressed in the form of a linear matrix relationship on homogeneous coordinates),...
