<name>iBUG face point dataset - All images</name>
<comment>This folder contains data downloaded from:
http://ibug.doc.ic.ac.uk/resources/facial-point-annotations/

The dataset is actually a combination of the AFW, HELEN, iBUG, and LFPW
face landmark datasets. But the iBUG people have aggregated it all together
and gave them a consistent set of 68 landmarks across all the images, thereby
turning it into one big dataset.

Note that we have adjusted the coordinates of the points from the MATLAB convention
of 1 being the first index to 0 being the first index. So the coordinates in this
file are in the normal C 0-indexed coordinate system.

We have also added left right flips (i.e. mirrors) of each image and also
appropriately flipped the landmarks. This doubles the size of the dataset.
Each of the mirrored versions of the images has a filename that ends with
_mirror.jpg.

Finally, note that the bounding boxes are from dlib's default face detector. For the
faces the detector failed to detect, we guessed at what the bounding box would have been
had the detector found it and used that.</comment>
