    摘要： A smoke detecting method is provided. The smoke detecting method includes steps of (a) capturing a video segment for a object and a background; (b) analyzing if an image of the object is moving; (c) analyzing a chrominance variance of the moving object with a corresponding background; (d) analyzing at least one of an edge blur of the image of the background and a flickering frequency of the moving object with its corresponding background; (e) comparing analyzed results obtained from the steps (b)-(d) to a smoke feature; and (f) determining if the moving object is a smoke.

    摘要： A smoke detecting method and system are provided. The smoke detecting method and system capture a plurality of images; determine whether a moving object exists in the plurality of images; select the images having the moving object to be analyzed; analyze whether the moving object is moving toward a specific direction and a displacement of a base point of the moving object; and determine the moving object as a smoke when the moving object is moving toward the specific direction and the displacement is less than a threshold value.
