| Abstract: | An edge detection algorithm of fire image based on wavelet modulus maxima and adaptive threshotd was proposed in this paper.In order to realize edge detection of fire image,after calculating the gradient modulus maxima of wavelet transform of fire image,adaptive threshold algorithm was used to remove false edge.This algorithm can implement edge detection efficiently from fire image with noise,which requires less amount of calculation,with the advantage of better robust and real-time.The experimental results... |
