Fig. 13 Some of the images from the BioID dataset, consisting of 1521 images, for which
the symmetry analysis was successful. We achieved an accuracy rate of 99.41%. The ground
truth symmetry axes is annotated in yellow, while the detected axes are annotated in red.

symmetry analysis failed. The ground truth symmetry axes are annotated in yellow, while the
detected axes are annotated in red.
