  The social conventions and expectations around the appropriate use of imaging
and video has been transformed by the availability of video cameras in our
pockets. The impact on law enforcement can easily be seen by watching the
nightly news; more and more arrests, interventions, or even routine stops are
being caught on cell phones or surveillance video, with both positive and
negative consequences. This proliferation of the use of video has led law
enforcement to look at the potential benefits of incorporating video capture
systematically in their day to day operations. At the same time, recognition of
the inevitability of widespread use of video for police operations has caused a
rush to deploy all types of cameras, including body worn cameras. However, the
vast majority of police agencies have limited experience in utilizing video to
its full advantage, and thus do not have the capability to fully realize the
value of expanding their video capabilities. In this white paper, we highlight
some of the technology needs and challenges of body-worn cameras, and we relate
these needs to the relevant state of the art in computer vision and multimedia
research. We conclude with a set of recommendations.
