I am reading this article about measuring similarity between x-rays and DRR's (2d projections from CT) and the article speaks about different measurement techniques accuracy vs. attraction range.
I can't find any information online on what "attraction range" means. Can someone point me in the right direction?
It seems to me that attraction range means the area which is searched for an optimal solution, so that a wider range of search is more robust and a smaller range is riskier. I'd appreciate confirmation of my understanding.
