Proper handling of continuous variables is crucial in healthcare research, for example, within regression modelling for descriptive, explanatory, or predictive purposes. However, inadequate methods ...

The B-spline curve and surface provide an accurate tool to record object shape. We present a biometric identification system through hand geometry measurements by using B-spline curves.

Quadratic Non-uniform hyperbolic B-spline curves with a local parameter are presented in this paper. The changes of a local shape parameter will only affect one curve segment. With the increase or ...
