Distributed Differential Evolution for the Registration of Remotely Sensed Images

Abstract

Abstract. This paper deals with the design and implementation of a software system based on Differential Evolution for the registration of images, and in its testing by means of a set of bidimensional remotely sensed images on two problems, i.e. mosaicking and changes in time. 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 comparison is effected against a publicly available tool, showing the effectiveness of our method.

A study on scale factor in distributed differential evolution

“…In [11][12][13], in order to solve some image registration problems a distributed DE (indicated here with DDE) has been proposed. This algorithm differs from PDE and IBDDE by the topology it uses.…”

“…In [11][12][13], it has been proposed to set l = 4, i.e. each node (such as the black disc in the Fig.…”

“…Following similar logic, Kozlov and Samsonov [23] proposes a distributed DE where the computational cores are arranged according to a ring topology and, during migration, the best individual of a sub-population replaces the oldest member of the neighboring population. In De Falco et al [11][12][13] a distributed DE has been designed for the image registration problem. In these papers, a computational core acts as a master by collecting the best individuals detected by the various subpopulations running in slave cores.…”

Distributed differential evolution with explorative–exploitative population families

“…In Falco et al [17,18,19], in order to solve and image registration problem a distributed DE (here indicated with DDE) has been proposed. This algorithm differs from PDE and IBDDE by the topology it uses.…”

“…In Refs. [17,18,19] a distributed DE has been designed for the image registration problem. In these papers, a computational core acts as a master by collecting the best individuals detected by the various sub-populations running in slave cores.…”
