A novel hybrid method for modelling leaf surface that combines Gaussian radial basis function (RBF) and Clough-Tocher (CT) methods to achieve a continuous surface is proposed by the author [20]. In this paper, we demonstrate the accuracy of the hybrid Gaussion RBF-CT approach by applying it to model the surface of frangipani and anthurium leaves. Furthermore, a comparison between the hybrid Gaussion RBF-CT method and the hybrid multiquadric RBF-CT method introduced by the author Oqielat et al. [17] is presented.
The development of the algorithm has been made to assist the understanding of leaf surface properties. It is found that the hybrid multiquadric RBF-CT surface fitting methodology produces more accurate and realistic leaf surface representation than using the hybrid Gaussion RBF-CT method.
