In order to enhance the night vision scene and saliency target in the fusion image,a fusion method of visible and infrared image is proposed. Firstly,the visible image is enhanced. Secondly,the base layer and the detail layer are obtained by using the constrained decomposition method for the enhanced visible image and infrared image. Thirdly,the local energy fusion rule is used on the base layer；the saliency map rule is used on the detail layer. Finally,the fusion detail layer and the base layer are superposed. The experiment shows that the proposed method achieves a satisfactory result from both subjective visual effects and objective image assessment.
