Figure 4

Automatic landmark annotation accuracy using an initial, point-based registration. (a) Box-and-whisker plots of the point localisation errors for automatic annotation of 50 skull landmarks on the 12 consomic Mus musculus specimens (read against the left-hand scale), using the second set of manual landmarks and an initial, point-based registration stage. The black squares and red crosses show, respectively, the percentage of points passing the outlier test and the percentage within the error threshold (read against the right-hand scale); only points passing the outlier test have been included in the box-and-whisker plots. (b) ROC curve of the true and false positive rates of points passing the outlier test; the operating point of the test is coincident with the y-axis.
