From: Assessing the application of landmark-free morphometrics to macroevolutionary analyses
Principal component plots (PC) for PC1 and PC2 obtained for the shape analysis using the “Poisson” meshes, comparing the results between (a) manual landmarking with 754 landmarks and sliding semilandmarks and the DAA method using kernel widths of (b) 40.0 mm, yielding 45 control points, (c) 20.0 mm, yielding 270 control points, and (d) 10.0 mm, yielding 1,782 control points
