Abstract

This method comprises the modelling of area and size (correlated and modelled with a Chapman-Richards growth function, usingfinallengthasoneparameter), �andfourshapedescriptors, �fromwhichtheentirecontour � canbereconstructedratherwellusingaspecificsplinemethodology . �Asanimprovementofthis � contour modelling method, a set of parameterized polynomials was used. To model the temporal kinetics of the shape, geodesics in shape spaces were employed. Finally it is shown how this methodology is integrated into the 3D modelling platform GroIMP.

基于非破坏性数字化和低参数形状演化的叶片生长重建，用于植物生长周期建模

提出了一种简单而有效的光度计方法，涵盖了从野外数据采集到二值化的所有步骤，并允许叶片轮廓建模。该方法包括面积和大小的建模(与Chapman-Richards生长函数相关并建模，使用最后一个参数)，以及四个形状描述符，从中可以使用特定样条方法构建整个轮廓。作为对这种轮廓建模方法的改进，使用了一组参数化多项式。为了模拟形状的时间动力学，采用了形状空间中的测地线。最后，展示了如何将这种方法集成到3D建模平台GroIMP中。
