针对空间对接背景下多源图像融合问题，提出一种基于SCDPT（shiftable complex directional pyra-mid transform）的分层图像融合策略。对于运动图像序列中运动目标由远到近过程中目标大小的变化，提出了一种分层融合的方法，将视觉特征明显的运动目标区域采用基于匹配度-区域内积能量的SCDPT融合算法，而非运动目标区域采用传统的融合算法。通过实验以及对实验结果的主观评价准则和客观评价准则，分析证明了图像的分层融合策略在标准图片和空间图片上都可以达到满意的融合效果。
針對空間對接揹景下多源圖像融閤問題，提齣一種基于SCDPT（shiftable complex directional pyra-mid transform）的分層圖像融閤策略。對于運動圖像序列中運動目標由遠到近過程中目標大小的變化，提齣瞭一種分層融閤的方法，將視覺特徵明顯的運動目標區域採用基于匹配度-區域內積能量的SCDPT融閤算法，而非運動目標區域採用傳統的融閤算法。通過實驗以及對實驗結果的主觀評價準則和客觀評價準則，分析證明瞭圖像的分層融閤策略在標準圖片和空間圖片上都可以達到滿意的融閤效果。

This paper proposes a layered image fusion strategy based on SCDPT (shiftable complex directional pyra-mid transform), which is under the background of the space docking. For a sequence of moving images, the size of moving target changes when it moves from far to near. This paper proposes a layered fusion method, in which the moving target region with obvious visual characteristics uses a fusion algorithm based on SCDPT with the image fusion rule based on matching degrees and region inner product energy, and the non-moving target region uses the traditional fusion algorithm. Finally, the experimental results of subjective evaluation criterion as well as objective evaluation criterion show that the layered image fusion strategy can achieve satisfactory fusion results both with standard pictures and space pictures.
