Abstract
Smoke detection based on video images includes performing background image modeling on a current image, to acquire a foreground image and a background image of the current image; acquiring one or more candidate areas in the current image used for detecting a moving object, based on the foreground image; calculating attribute information of a candidate area corresponding to the current image and/or the background image; and determining whether there exists smoke in the candidate area according to the attribute information. The smoke can be detected quickly and accurately through video images, but also the detection accuracy of video-based smoke detection when light changes and at complex environments can be provided.
