L"2-norms are often used in the multi-degree reduction problem of Bezier curves or surfaces. Conventional methods on curve cases are to minimize @!"0^1@?A(t)-C(t)@?^2dt, where C(t) and A(t) are the given curve and the approximation curve, respectively. A much better solution is to minimize @!"0^1@?A(@f(t))-C(t)@?^2dt, where A(@f(t)) is the closest point to point C(t), that produces a similar effect as that of the Hausdorff distance. This paper uses a piecewise linear function L(t) instead of t to approximate the function @f(t) for a constrained multi-degree reduction of Bezier curves. Numerical examples show that this new reparameterization-based method has a much better approximation effect under Hausdorff distance than those of previous methods.
