We denote this dataset by ”stable triangles”. Also, we created a dataset ”random triangles” which consists of 50 triangles, whose vertices are uniformly distributed within a unit cube. 1 Methods Point-Based Rigid Registration Prior to applying different techniques from statistical shape theory, we employ 3D point-based rigid registration (translation, rotation) to transform all 3D BAC-triangles onto the x-y plane (reference system). 3D point-based registration can be formulated as follows. Given k source points pi , and k target points k qi , the task is to find a rigid transformation R such that i=1 qi − pi ◦ R 2 is minimized.

Results after 3D point-based registration: Datasets AR1 (a), AR2 (b), stable triangles (c) and random triangles (d) their |λ2 | values are larger than |λr |. 34. The listed values for F in Tab. 1 reveal that all datasets except AR2 and AR4 are not uniformly distributed. This confirms the result using the complex Bingham distribution and the |λ2 | values. 3). Table 1. Computed absolute values of λ2 and result of the uniformity test for the real datasets. The last row lists the number of BAC-triangles for each dataset (sum: 457).
