Image processing and analysis are generally seen as operations on
two-dimensional arrays of values. There are however a number of fields where
images of higher dimensionality must be analyzed. Good examples of these are
medical imaging and biological imaging. numarray is suited very well
for this type of applications due its inherent multi-dimensional nature. The
numarray.nd_image packages provides a number of general image
processing and analysis functions that are designed to operate with arrays of
arbritrary dimensionality. The packages currently includes functions for linear
and non-linear filtering, binary morphology, B-spline interpolation, and object
measurements.
