Abstract: This paper presents a smoke foreground segmentation algorithm based on temporal-spatial analysis together in early forest fire smoke image sequences.Firstly，we analyze the instantaneous dynamical data and cumulated dynamical data.Secondly，after binarization and morphology processing，we obtain the smoke foreground contour.And then，the author can extract the smoke foreground by scanning the smoke foreground contour and filling the smoke foreground mask.Experiment results show that this method can successfully segment the smoke foreground from the early forest fire smoke image sequences with less time.
