Bayesian quantile semiparametric mixed-effects double regression models
Statistical Theory and Related Fields, 2021 Semiparametric mixed-effects double regression models have been used for analysis of longitudinal data in a variety of applications, as they allow researchers to jointly model the mean and variance of the mixed-effects as a function of predictors ...

The weighted v-spline as a double knot B-spline
, 1991 The local support basis representation of the ‘weighted v-spline’ is derived in terms of double knot cubic B-splines, so providing a convenient form for computing and analysing the ...

A rational cubic spline with tension
, 1989 A rational cubic spline curve is described which has tension control parameters for manipulating the shape of the curve. The spline is presented in both interpolatory and rational B-spline forms, and the behaviour of the resulting representations is ...

Efficient algorithms for robust generalized cross-validation spline smoothing
, 2010 Generalized cross-validation (GCV) is a widely used parameter selection criterion for spline smoothing, but it can give poor results if the sample size n is not sufficiently large.

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)

A New Method for Deformation of B-spline Surfaces
, 2010 This paper presents an efficient method for deforming B-spline surfaces, based on the surface energy minimization. Firstly, using an analogy between the B-spline surface patch and the thin-plate element of the finite element method, and applying external

, 1981 This paper gives a definition for the convexity of B-spline surfaces and points out the conditions on which the convexity depends. A back shift smoothing method is introduced. This method is built on the basis of the convexity conditions.
