Curve fitting using quintic trigonometric Bézier curve

Abstract

Curve fitting is an important process. Curve fitting is the process of constructing a curve that is closest to data series. In this research, curve fitting using quintic trigonometric Bézier curve (QTBC) with two shape parameters will be applied. Shape parameters will act as shape enabler in order to make the curves more flexible. Different degrees of parametric continuity are applied accordingly to connect each segment of two-dimensional objects to produce a smooth curve fitting. The curve fitting is made easier due to the presence of two parameters, making QTBC as the suitable tool for curve fitting. To analyse the performance, it is applied to three various objects that exhibit different features.
