Application of Legendre–Bernstein basis transformations to degree elevation and degree reduction [PDF]

open access: yesComputer Aided Geometric Design, 2002
We study the relationship of transformations between Legendre and Bernstein basis. Using the relationship, we present a simple and efficient method for optimal multiple degree reductions of Bezier curves with respect to the L2-norm.
