Introduction
Describes a method for counting and localizing people in an area
Using Camera Sensor Networks
Is a light weight method
Using Motion histogram
Low cost system
Easy to install
Requires little or no on-site calibration

Previously used systems
PIR(Passive Infrared Sensors)- measures infrared(IR) light radiating from objects in its field of view
Pressure sensitive floor tiles
Camera based systems-use pattern matching

DISADVANTAGES
Requires a laborious installation process
May require precise onsite calibration
Feature extraction and matching processes can be computationally
Complex
Background differencing problems

Back ground differencing &Frame differencing
Problem with frame differencing

Histogram
Histogram(cont)
Image Histogram
Motion Histogram

Histogram Structure

Example -histogram frame.
