Several applications such as multi-atlas segmentation require frequent iteration over multiple image volumes at the same time. Doing so with the regular ITK iterators is tedious and error prone as it requires updating each iterator at end of each iteration. [...]

We present a generic interpolator for label images. The basic idea is to interpolate each label with an ordinary image interpolator, and return the label with the highest value. This is the idea used by the itk::LabelImageGaussianInterpolateImageFunction [...]

We introduce a bio-inspired dynamic deformable (DET) model based on the equation of dynamics and including temporal smoothness constraints. The behaviour and characteristics of the dynamic DET model is studied in the context of the semi automatic [...]
