Idiap Research Institute -- March 2013

Multi-PIE manual annotations from the biometric group at Idiap, organized in the same way as the (multiview) images of the original Multi-PIE database

These annotations were performed for the following research article:
1. "A Scalable Formulation of Probabilistic Linear Discriminant Analysis: Applied to Face Recognition",
Laurent El Shafey, Chris McCool, Roy Wallace, Sebastien Marcel
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2013

Furthermore, if you use them, we would appreciate if you cite this publication.


The annotations are in the following format:

ISSUE with images from cameras 08_1 and 19_1:
Please note that in the original database all images from cameras 08_1 and 19_1 are upside down. 
For these cameras, the annotation was performed on flip/flop images as follow:
% if (camera == "08_1" or camera == "19_1") convert -flip -flop image_source image_target
