Workstation-based shape matching experiments

There are a variety of mathematical formulations for specifying smooth curves using spline techniques. A controlled experiment has been performed to test the hypothesis that the mathematical formulation selected will influence the ease with which two-dimensional shape matching can be performed in a workstation environment. The experiment compares four mathematical formulations (B-splines, Bezier, Cardinal, and C/sup 2/ interpolating) for specifying smooth curves through the placement of control vertices.<
