Lightweight People Counting and Localizing for Easily Deployable Indoors WSNs

T. Teixeira, A. Savvides
2008 IEEE Journal on Selected Topics in Signal Processing  
The motion histogram is an averaged shifted histogram that estimates the distribution of people in a room given the above-threshold pixels in a frame-differenced "motion" image.  ...  Our implementation on sensor nodes uses a custom sensor board with a commercial off-the-shelf camera, but the motion histogram is designed to easily adapt to ultralow-power address-event motion imagers  ...  More importantly, their system does not handle rooms larger than the single stereo-pair's field-of-view.  ...
