【摘要】 针对目前小波域内多聚焦图像融合所存在的问题,提出一种基于M带小波变换的图像融合方案。由于M带小波变换域在能量紧致性和方向选择性等方面都比传统二带小波更有优势,综合考虑图像在M带小波变换域的多尺度和多方向性信息以及局部区域的相关特性,提出了一种新的小波域图像融合策略——基于多子带联合窗口特性的图像融合。仿真实验分析表明,该文算法的结果不论在视觉效果还是在信息量指标方面都优于传统的二带小波。更多还原

【Abstract】 In this paper,a multi-focus image fusion method based on M-band Wavelet is proposed.M-band wavelet transform domain has its superiority to 2-band wavelet transform domain in energy compaction and direction selection. Considering both the multi-scale-multi-direction information and the correlation property in M-band wavelet domain,an image fusion scheme based on cross-band-window is brought forward.The simulation results in multi-focus image fusion verify the superiority of the proposed method to the method based on 2-band wavelet in both the subjective and objective evaluation.更多还原
