Construction of B-spline surface from cubic B-spline asymptotic quadrilateral
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Asymptote is widely used in astronomy, mechanics, architecture and relevant subjects. In this paper, by analyzing the Frenet frame and the Darboux frame of a curve on the surface, the necessary and sufficient conditions for a quadrilateral boundary being

B-Spline-ORB Feature Point Extraction Algorithm
Journal of Harbin University of Science and Technology, 2022 Aiming at the problem of poor scale invariance of traditional ORB algorithms, this paper proposes an ORB algorithm based on image golden tower. Firstly, Gauss image pyramid and B-Spline image pyramid are studied, and the two image pyramids are discussed ...

Regularization of B-spline objects [PDF]
Computer Aided Geometric Design, 2011 By a d-dimensional B-spline object (denoted as ), we mean a B-spline curve (d = 1), a B-spline surface (d = 2) or a B-spline volume (d = 3). By regularization of a B-spline object we mean the process of relocating the control points of such that they approximate an isometric map of its definition domain in certain directions and is shape preserving ...

Journal of Approximation Theory, 2017 We introduce B-splines on the line of quaternionic order $B_q$ ($q$ in the algebra of quaternions) for the purposes of multi-channel signal and image analysis. The functions $B_q$ are defined first by their Fourier transforms, then as the solutions of distributional differential equation of quaternionic order.

Journal of Approximation Theory, 1996 The authors define certain combinations of multiquadrics, denoted as \(\Psi\)-splines, and investigate their properties. In particular, the strong analogy between these \(\Psi\)-splines and the usual polynomial B-splines is pointed out at several places.
