The Problem

  • Brian Avants and his group identified that the computation of Mutual Information metric produces inconsistent results under different threading conditions. They narrowed the problem to an accumulation of errors.
  • This might be a situation where a more aware process for accumulating a large number of small terms could provide a solution.
  • Brian will post the specific lines of code in ITK where the problem is suspected to originate from.
