Abstract: Background prediction is effective method of dim and small target detection.According to requirement of dim and small target detection,aiming at defects of existing algorithm,on the basis of analyzing the characteristic of image of dim and small target and its wavelet,a kind of background prediction algorithm of small and dim target detection based on wavelet analysis is designed and implemented.Flow chart of the algorithm is given,the algorithm is described and tested,the test results identify that the algorithm has some merits that speed is high and capability of anti-noise is robust.

Key words: wavelet analysis, dim and small target, target detection, background prediction
