[Insight-developers] question about CovarianceSampleFilter

[Arnaud Gelas]

Hi all,

In itk::CovarianceSampleFilter, the mean is computed as the same type  
as the TSample type. So if inputs are vector of unsigned char, the  
mean is a vector of unsigned char...
While the mean is assumed to be as the same type as TSample, the  
covariance matrix coefficients are in double, not in the same type as  
the input.

Shouldn't the mean' components in double (to be consistent with what  
has been done for the covariance matrix)?

Thanks,
Arnaud
