[Insight-users] minimum of two image regions

[Andreas Schuh]

Hi David,

have a look at the ImageRegion(WithIndex)(Const)Iterator classes.  
These are designed for iterating just over a certain ImageRegion of an  
Image.

But if you want to calculate the minimum or maximum value within a  
certain region, you should also be able to use either the  
MinimumMaxiumImageCalculator resp. MinimumMaximumImageFilter with the  
requested region set to the your specific "sub"-image region.
