Contour based smoke detection in video using wavelets
(IEEE, 2006-09)This paper proposes a novel method to detect smoke in video. It is assumed the camera monitoring the scene is stationary. The smoke is semi-transparent at the early stages of a fire. Therefore edges present in image frames ... -
Wavelet based real-time smoke detection in video
(IEEE, 2005-09)A method for smoke detection in video is proposed. It is assumed the camera monitoring the scene is stationary. Since the smoke is semi-transparent, edges of image frames start loosing their sharpness and this leads to a ...
