[ITK] [ITK-users] Fwd: MeanSquaresImageToImageMetricv4 with unsigned char PixelType results in error C2440

[Matt McCormick]

Hi Andrew,

This itk::ConceptCheck [1] says that the pixel values must be float to
be used in itk::MeanSquaresImageToImageMetricv4 -- use an
itk::CastImageFilter to change the pixel type.

HTH,
Matt
