Recursive B-spline approximation using the Kalman filter
Engineering Science and Technology, an International Journal, 2017 This paper proposes a novel recursive B-spline approximation (RBA) algorithm which approximates an unbounded number of data points with a B-spline function and achieves lower computational effort compared with previous algorithms.

New Cubic B-Spline Approximation for Solving Linear Two-Point Boundary-Value Problems
Mathematics, 2021 In this study, we introduce a new cubic B-spline (CBS) approximation method to solve linear two-point boundary value problems (BVPs). This method is based on cubic B-spline basis functions with a new approximation for the second-order derivative.

Contour Detection of Mammogram Masses Using ChanVese Model and B-Spline Approximation
International Journal of Interactive Multimedia and Artificial Intelligence, 2017 ChanVese model segmentation has been applied for contour detection of mass region in mammogram in our previous work. Available information of the desired object contour is used, in this paper, for B-spline approximation. The mass region boundary (contour)

Dual generalized B-spline functions and their applications in several approximation problems
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015 A new construction method of dual generalized B-spline functions is presented in this paper. Due to the importance of generalized B-splines, several interesting applications of these dual functions in Computer Aided Manufacturing are also given.

APPLICATION OF B-SPLINE METHOD IN SURFACE FITTING PROBLEM [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Fitting a smooth surface on irregular data is a problem in many applications of data analysis. Spline polynomials in different orders have been used for interpolation and approximation in one or two-dimensional space in many researches. These polynomials

Comparison of selected splines for stem form modeling: A case study in Norway spruce
Annals of Forest Research, 2014 Natural cubic spline has been frequently used to represent stem forms, with other spline types rarely involved. Splines are a large class of functions and there are many other spline types which might serve that purpose.

Thin plate splines for transfinite interpolation at concentric circles
Mathematical Modelling and Analysis, 2013 We propose a new method for constructing a polyspline on annuli, i.e. a C 2 surface on ℝ2 \ {0}, which is piecewise biharmonic on annuli centered at 0 and interpolates smooth data at all interface circles.

SPLINE APPROXIMATION FOR ZADEH'S EXTENSIONS
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2009 In this paper we show an approximation for [Formula: see text], where u is a fuzzy interval and [Formula: see text] is obtained from a continuous function f applying the Zadeh's extension principle. In this process, we used a decomposition for u and the linear spline function for the approximation of f.
