The very first step in many facial analysis systems
is face detection. Though face detection has been studied for
many years, there is not still a benchmark public database to
be widely accepted among researchers for which both color
and depth information are obtained by the same sensor. Most
of the available 3d databases have already automatically or
manually detected the face images and they are therefore
mostly used for face recognition not detection. This paper
purposes an RGB-D database containing 1581 images (and
their depth counterparts) taken from 31 persons in 17 different
poses and facial expressions using a Kinect device. The faces in
the images are not extracted neither in the RGB images nor in
the depth hereof, therefore they can be used for both detection
and recognition. The proposed database has been used in a face
detection algorithm which is based on the depth information
of the images. The challenges and merits of the database have
been highlighted through experimental results.
