Automatic landmark annotation accuracy using a mixed-genera database. (a) Box-and-whisker plots of the point localisation errors for automatic annotation of 40 mandible landmarks on the data set of 14 rodent specimens (read against the left-hand scale). 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 dashed line shows the operating point.
