“…The remaining three points correspond to specific anatomical landmarks, which need to be defined in order to match the SSMs to the radiographic scene. These landmarks are commonly used in literature [21], [22], [23] and are depicted in Fig. 1.…”

“…Therefore, intra-and interobserver variability is an important factor that should be taken into account when using landmark-based clinical parameters. Several studies have been performed to assess the reproducibility of landmark identification on CT or MR (-based) images and the corresponding morphological parameters (Cerveri et al 2010, Lerner et al 2003, Nofrini et al 2004, Subburaj et al 2009, Victor et al 2009, Yoshino et al 2001), see Table 1. A direct comparison between studies is not feasible, because of the different methods that are used, but their results indicate that mean variabilities of 2-3 mm/° are not uncommon for some of the landmarks and parameters.…”

“…For such reasons, surface curvature has been widely proposed as a shape descriptor and investigated for the automatic extraction of MCL. It has been applied to the analysis of patterns of cranial morphological differentiation in rodent species [30] and for MCL detection in femur and pelvic bone models [29,31]. However, in using surface curvature to detect MCL in bone shapes, two main issues have to be addressed.…”

Specifically, the surface curvature is an invariant, independent of position and orientation, that can be exploited for reliable detection of geometric features as concavities and convexities.…”
