小波变换在图像融合中的应用研究

Research on application of wavelet transform in image fusion

小波变换由于良好的多分辨率分析特性,常被应用到红外和可见光图像融合中。通过深入研究小波基的紧支集和正交性等特性以及小波变换层数对融合结果的影响,结合对融合实验的分析,综合考虑图像背景信息、目标区域和实时性等因素,总结出了根据不同的融合目的来应用小波变换的方法,为实际处理中小波变换的应用提供了参考。

Because of the good multi-resolution analysis characteristic, wavelet transformation is often applied in the fusion for infrared and optical images. The compact supported set and the orthogonality of wavelet basis and the influence of wavelet transform layers on fusion result were studied. Combining with the analysis of fusing experiment and considering the image background, object area and real-time, according to different application proposes, some methods on the application of wavelet transformation are proposed, which provides some references for wavelet application.
