Distributed Differential Evolution for the Registration of Satellite and Multimodal Medical Imagery

In this chapter, a parallel software system based on differential evolution for the registration of images is designed, implemented and tested on a set of 2-D images in two different fields, i.e. remote sensing and medicine. Two different problems, i.e. mosaicking and changes in time, are faced in the former application field. Registration is carried out by finding the most suitable affine transformation in terms of maximization of the mutual information between the first image and the transformation of the second one, without any need for setting control points. A coarse-grained distributed version is implemented on a cluster of personal computers.
