Summarization: Evolutionary algorithms have been used recently as an alternative in image registration, especially in cases where the similarity function is non-convex with many local optima. However, their drawback is that they tend to be computatio

Summarization: Evolutionary computation has been widely used in intensity-based medical image registration due to its ability to deal with the large number of the local minima which the conventional optimization methods fail. Despite this successful
