Abstract: For the indoor environment as the application background，this paper designs the feature fusion flame detection algorithm with static and dynamic flame features，which gives the quick decision to the fire flame.Firstly，the paper makes the motion detection to the video image，extracts the color feature，and creates a new color criterion in HIS space，then gets round and peak number of fire flame area.Finally，it researches on the characteristics of the flame flicker，taking all these features as neural network input，and ultimately uses of weighted fusion algorithm to determine whether it is the fire flame.

Key words: motion detection, flame detection, threshold estimation, feature fusion
