我们说明形状模式分析作为一个简单的，但功能强大的技术来简洁地描述复杂的生物形状和它们的动态。我们的特征波动弯曲波的跳动鞭毛和重建的极限环鞭毛振荡，特别注意的周期性的角度数据。作为第二个例子，我们分析非凸边界轮廓的滑翔扁形虫，这使我们能够暴露刻板的身体姿势，可以涉及到两个不同的运动机制。此外，基于主成分分析的形状模式分析允许区分不同的扁形虫物种，尽管大的运动相关的形状变化。因此，复杂形状动力学的特征在于随时间变化的少量形状分数。我们提出这种方法使用描述性的例子，解释抽象的数学图形的方式。
We illustrate shape mode analysis as a simple, yet powerful technique to concisely describe complex biological shapes and their dynamics. We characterize undulatory bending waves of beating flagella and reconstruct a limit cycle of flagellar oscillations, paying particular attention to the periodicity of angular data. As a second example, we analyze non-convex boundary outlines of gliding flatworms, which allows us to expose stereotypic body postures that can be related to two different locomotion mechanisms. Further, shape mode analysis based on principal component analysis allows to discriminate different flatworm species, despite large motion-associated shape variability. Thus, complex shape dynamics is characterized by a small number of shape scores that change in time. We present this method using descriptive examples, explaining abstract mathematics in a graphic way.
