Currently QmitkImageStatisticsView::CheckForSameGeometry and QmitkImageStatisticsView::GenerateROIPredicate check to pendantic for same geometry (default mitk::eps == 1e10^-14). This e.g. leads to exclusion of images that differ only in the tenth decimal place of an axis vector, which can happen due to rounding effect when storing and loading data. E.g. in one case the parameter fits could not be analysed together with the input image as the differ like noted above.

Proposed solution: Lower the demanded precision used in the named function.
E.g. MaskUtilities that is used by the statistic calculator internally uses only a precision of 0.001 for direction and coordination tolerance in its checks and filters. Spacing is there still checked with mitk::eps but I think thats also to pendantic.
If we use a value it shouldn't be a magic number, but a public constant(s), that is used in the view as well in MaskUtilities to be sure that all use the same and it is clear what they use.
