We investigate a streamlined method for compression, approximation
and fast interpolation of gait analysis data using Catmull-Rom Splines.
We are interested not only in raw compression, but also extracting the
most useful data from an animation for subsequent manipulation. Our
method allows compression approaching 85 percent while the resulting
animation remains indistinguishable by humans from the original animation,
resulting in significant memory savings, while the untransformed
compressed animation has possible usefulness in gait retargeting
