Wireless Webcam Based Omnidirectional Health Care Surveillance System

This paper proposes an efficient omnidirectional surveillance system for health care purposes. The proposed surveillance system is used to detect fainted person at health care centers such as old folk's home, hospital, and handicapped center and is located at the place with good light condition. When a fainted person is detected, it send immediate signal and thus alerts/treatments can be carried out. In this system, a wireless webcam attached with a hyperbolic mirror is used to capture the omnidirectional scene at health care centers. The captured scenes are then fed into a laptop computer for image processing, faint detection and alarm purposing. Log-polar mapping is used to map the omnidirectional images into panoramic images. An effective faint detection algorithm is designed to detect a fainted human at health care centers. Experimental results show that the proposed wireless omnidirectional surveillance system achieves high accuracy (92.99 % out of 10000 testing images under good light condition) in monitoring a selected private nursing home. The observed significances of this new proposed surveillance system include: omnidirectional coverage, high data compression output images, wireless, and with effective faint detection capability.
