摘　　要：针对空间对接背景下多源图像的融合,提出一种基于SCDPT的图像融合算法和一种基于匹配度?区域内积能量的图像融合规则,并将其应用于SCDPT分解产生的高频系数融合中。将改进后的融合规则用于SCDPT算法中,对标准图像和空间图像进行融合实验。研究结果表明:与传统的小波方法和UDCT方法比较,基于改进融合规则的SCDPT方法在客观评价指标及主观效果上均优于对比方法。An image fusion algorithm based on SCDPT was proposed,which is under the background of the space docking.The image fusion rule was proposed based on matching degrees-integrated energy region,and applied to the method to the high-frequency coefficients created by SCDPT decomposition.The experimental results of subjective evaluation criterion as well as objective evaluation criterion show that the improved fusion rule for SCDPT algorithm can achieve satisfactory fusion results both with standard pictures and space pictures compared to the traditional wavelet method and UDCT.
