Remote sensing image fusion for dim target detection

In order to resolve the problem of dim target detection, a novel approach based on image fusion and mathematical morphology was proposed. First, the characteristics of steerable pyramid were described. Second, the original images were fused using steerable pyramid transform technique based on effective fusion scheme. The targets can be enhanced and clearer in fused image. Finally, mathematical morphology method was applied to detect the target based on the fused image. The experimental results show that the effect of our method is satisfactory.
