[Insight-users] itk::PCAShapeSignedDistanceFunction

[Lydia Ng]

Lucas,

I don't believe there is apart from polling one pixel at a time.

Even if you use a combination of filters
SpatialFunctionImageEvaluatorFilter->BinaryThresholdImageFilter you will
still need to eventually visit every pixel to find which is within =
range.
