[ITK-users] Registration with Spatial Masking

[suneeza hanif]

Hello Dženan,

Thank you for your response.

I have tried with larger mask but I get same error.

Secodly, when I use itk::ImageSpatialObject instead of
itk::ImageMaskSpatialObject
I do not get this error but then mask is not activated because even when I
take mask of size (0,0) registration process still keeps on running.

Best Regards,
Suneeza
