Optimal normalized totally positive basis
WebFeb 1, 2024 · Han and Zhu expressed that the cubic trigonometric Bézier basis with two shape parameters forms an optimal normalized totally positive basis and showed that the basis is not suited for curve design from the blossom point of view. Cubic ... The quintic trigonometric basis functions have the following properties : WebFeb 1, 2010 · A blending basis that is TP is said to be a normalized totally positive (NTP) basis. It is well known that (cf. Peña, 1999) the bases providing shape preserving representations are precisely the NTP bases and that a space with an NTP basis always has a unique normalized B-basis, which is the basis with optimal shape preserving properties.

WebIn this study, the proposed DT B-like basis function forms a set of optimal normalized totally positive bases under the framework of the ECC-space, which leads to the DT BB-spline basis function and the DT-BB-like basis function. Curve and surface construction and related discussions are based on these kinds of basis functions.

Similarly to the classical Bernstein polynomials of
WebFeb 1, 2010 · Compared to the usual progressive iteration approximation, our method has a faster convergence rate for any normalized totally positive basis, which is achieved by choosing an optimal value for the weight. For weighted progressive iteration approximations, we prove that the normalized B-basis of a space provides the fastest convergence rate ... Webresembling the good properties of the Bernstein basis. When the space has a normalized totally positive basis, the Bernstein-like bases are provided by the normalized B-bases, which present optimal shape preserving properties (see [2], [3], [12]). A totally positive basis (b0;:::;bn) of a space U is a B-basis if for any other totally positive ...
