Sample variance was calculated for each landmark, and differences in landmark variances were compared across modules with a non-parametric Kruskal-Wallis test.
There were also some differences in landmark coverage and dispersion between this and prior studies.
We performed groupwise BLDA to identify specific differences in landmark morphology between the sSCA groups.
Generalised Procrustes Analysis (GPA) was performed on landmark configurations (each consisting of 63 x, y and z coordinates of 21 facial landmarks) in order to remove differences in landmark positions attributable to translation and rotation.
In all batch applications, we have been interested in the coordinates of landmark points, rather than curve locations per se.
Table 1 shows the linear moving distance of each landmark points in ManMoS simulation.
This shape descriptor does not depend on landmarks or keypoints, avoiding the manual, and many times difficult, definition of these landmark points in a set of images.
In this case, 23 landmark points describe the outer edge of the pubis bone, and 8 landmarks describe the inner edge.
Anthropometric distances between landmark points measured in world coordinate system form a constraint set.
That was the difference in the points".
