Abstract

We propose two methods for model selection for the Dubuc-
Deslauriers family of subdivision schemes. In particular, we study
model selection under the statistical method of cross-validation and
the geometric method of minimizing the absolute discrete total curvature.
Our results show that schemes with large support and arity
can be better models of noisy data. Our findings give a justification
to the continuing research on large support and large arity schemes,
even though currently such schemes are rarely used in practice.
