Fuzzy Intuitionistic Alpha-cut Interpolation Rational Bézier Curve Modeling for Shoreline Island Data [PDF]
Malaysian Journal of Fundamental and Applied Sciences, 2023 The problem of uncertain data cannot be solved by conventional methods, which results in inaccurate data analysis and prediction. During the data collecting phase, ambiguous data are often collected, but they cannot be used immediately to generate ...

How Null Vector Performs in a Rational Bézier Curve with Mass Points
GeometryThis article points out the kinematics in tracing a Bézier curve defined by control mass points. A mass point is a point with a non-positive weight, a non-negative weight or a vector with a null weight.

Two Simulated Annealing Optimization Schemas for Rational Bézier Curve Fitting in the Presence of Noise [PDF]
, 2016 Fitting curves to noisy data points is a difficult problem arising in many scientific and industrial domains. Although polynomial functions are usually applied to this task, there are many shapes that cannot be properly fitted by using this approach.

Limit properties of rational Bézier curves with mixed weights(具有混合权函数的有理Bézier曲线的极限性质)
Zhejiang Daxue xuebao. Lixue banThe weights of a rational Bézier curve play a crucial role in shape modification of the curve. As the weight of a rational Bézier curve approaches infinity, the curve tends towards the corresponding control point.
