Collection of Facial Images: Grimace
Acquisition conditions
A sequence of 20 images per individual was taken, using a fixed
camera. During the sequence the subject moves his/her head and
makes grimaces which get more extreme towards the end of the
sequence. Otherwise the setup is similar to faces95. There is
about 0.5 seconds between successive frames in the
sequence.
