The new algorithm based on wavelet transform modulus maxima was presented to resolve the problem of weak infrared point targets detection under the complicated background of sea and sky. All the singularity points were got through the wavelet transfrom modulus maxima. The algorithm eliminates the complicated background of clouds, offing and sea antenna, enhances the ability of point target detection in single frame. Experimental results show that the algorithm can detect the point targets with SCR of 2.
