| Description: | The task is to align a sequence of N images onto a common reference. It is possible to register all images simultaneously, or all possible N^2 pairs but it is very computationally expensive. On the other hand, it is enough to register N-1 pairs and compose the transformations, which is fast but may lead to suboptimal accuracy. We shall (theoretically and practically) explore various ways of choosing the subsets of image pairs to register and how to estimate the individual deformations. |
