Increased use of three‐dimensional (3D) imaging data has led to a need for methods capable of capturing rich shape descriptions. Semi‐landmarks have been demonstrated to increase shape information but placement in 3D can be time consuming, computationally expensive, or may introduce artifacts. This study implements and compares three strategies to more densely sample a 3D image surface.

比较半标志性方法分析三维颅骨形态

越来越多地使用三维（3D）成像数据，因此需要能够捕获丰富形状描述的方法。已经证明了半地标可以增加形状信息，但是将其放置在3D中可能很耗时，计算量大或可能会引入伪影。这项研究实施并比较了三种策略来更密集地采样3D图像表面。
