摘要: Abstract The μ-basis of a rational curve/surface is new algebraic tool which plays an important role in connecting the parametric form and implicit curve/surface. However, most results for μ-bases are presented proper parametrizations. In this paper we consider improper planar curve. Based on known properties results, design two reparametrization algorithms using μ-basis. inversion, degree induced map implicitization formulas also derived.
