Number of leaves (terminal taxa) in each of 1614 source tree images (blue) and number of leaves recovered-from each image (orange). The modal number of taxa recovered per image was 12, the median was 13, and the mean was 13.96. The modal number of taxa not recovered from the trees was 2, the median was 5 and the mean was 7.15. The image mining process is lossy since most output tree files did not recover all of the taxa from the source image.
