ABSTRACT
A lightweight method for counting and localizing people using camera sensor networks is described in this article. a motion histogram is made use of by the algorithm for detecting the people based on motion and size criteria.the distribution of people in a roomis estimated by the motin histogram, given a threshod vaueof the pixels in a frame-differenced motion´ image. Ths the motion histogram is an averaged shifted histogram. good detection rates at low computational complexity is provided by the algorithmfor the users. The details of our design is described in the artcle and the results of the simulation of the The
resulting histogram and counting algorithm is also done . The cidcuit desribed is implemented in a iMote2 sensor nodes for te purpose of field testing. An off-the-shelf camera is used along with a a custom
sensor board. Thescenario involves ultralow-power address-event motion imagers and the motion histogram is designed to easily adapt to it.
