提出了一种简单的基于三角形网格的图像编码器，并给出了几种网格生成方法，其中一些是以前提出的，一些是新的。然后，我们的编码器是用来评估各种网格生成方法的性能。我们提出的网格生成计划，灵感来自工作的加兰和Heckbert，表现最好。线性和Clough-Tocher插值的性能进行了比较。线性插值被发现比Clough-Tocher插值执行更好，后者执行更差，主要是由于过冲/下冲附近的图像边缘。
A simple image coder based on triangle meshes is proposed, and several mesh-generation methods are presented, some previously proposed and some new. Then, our coder is used to evaluate the performance of the various mesh-generation methods. One of our proposed mesh-generation schemes, inspired by the work of Garland and Heckbert, is shown to perform best. The performance of linear and Clough-Tocher interpolation is also compared. Linear interpolation is found to perform better than Clough-Tocher interpolation, with the latter performing more poorly largely due to overshoot/undershoot near image edges.
