Hi Bill,

  look at itkImageToImageMetric::SetMovingImageMask() and how m_MovingImageMask
is used in derived classes in their GetValue() method. This way you can setup a spatial
object that decides whether pixel is used in metric computation. One of spatial objects
is an image mask. Isnt it what you are looking for?

# To be more specific on what I am trying to accomplish, here are my
# 2 input images:

# fixed:

# The violet pixels in the moving image are those pixels that should not be taken
# into account
# for registration. The 2 original images are fairly big (~4K x ~2K) and initial
# pixel distances
# is about 10-30 pixels.
# 
# Any suggestion on how to tackle this multi-modal registration will be welcomed,
# in terms 
# of metric, optimizer, transformation, etc. etc.
