The characteristics of small targets, noise and background in IR image are analysed. Because the small target is often corrupted by high noise after high pass filters, a peakvalue detection algorithm with wavelet transformation is presented basesd on the softthreshold denoising method proposed by Donoho. The simulation results show that the proposed algorithm can effectively restrain the residual high noise filtered with high pass filter and detect the small target
