Abstract: As a new network model, Pulse Coupled Neural Networks（PCNN） has been widely used in many fields. Aiming at the insufficient of traditional image fusion by pulse coupled neural networks algorithm, a novel adaptive PCNN image fusion algorithm is proposed. Two features are used as external stimulus of PCNN to extract the complementary information of source images. The linking strength parameters of PCNN are determined adaptively according to contrast of source images. Through analyzing the traditional PCNN algorithms in obtaining the optimal fusion result, a novel method is proposed which can acquire the optimal fusion result by comparing the structural similarity of the fused image at each iteration. Experimental results for visible and infrared images show that the proposed algorithm is effective for image fusion.
