 Alternatively, biometrics can be divided into physiological and behavioral
 traits. Physiological traits include faces, fingerprints, and irises; speech
 and gait are behavioral.  Face and gait recognition are the most relevent
-biometrics for this paper as they both are unobtrusive and rely on image
-processing.  Gait recognition usually involves determining the outline of a
-person from an image~\cite{bio-survey}, but algorithms similar to gait
-recognition have been developed for range cameras as well~\cite{gomez:hgbu11}.
-Face recognition receives a lot of attention from the research
-community~\cite{face-survey}, also including at least one example incorporating
-a range camera~\cite{gordon91}.  Since behavioral traits typically are more
+biometrics for this paper as they both can be collected passively and involve
+image processing.  Gait recognition usually involves determining the outline of
+a person from an image to measure gait, but can also be measured from floor
+sensors or wearable sensors~\cite{gait-survey}.  Face recognition can be broken
+down into three parts: face detection, feature extraction, and identification;
+these three parts are studied both together and separately~\cite{face-survey}.
+We will compare skeleton recognition to face recognition in this paper for the
+following two reasons.  First, behavioral traits typically are more
 characteristic as opposed to unique for identification beyond a certain
-scale~\cite{seven-issues}, we will compare the results of skeleton recognition
