基于小波变换的数字图像融合研究

摘要

介绍了小波变换的基本理论和图像融合的一些方法，着重分析了基于小波变换的图像融合方法，通过实验比较了三种融合方法（简单图像融合、塔式分解的图像融合、小波变换的图像融合）对平硐左右壁的应用.试验结果表明，小波变换在数字图像融合中的应用切实可行、效果好、有很强的实用价值，有较好的应用前景。%The thesis introduces the basic theory of wavelet transformation and some methods of image fusion. It fucuses on the analysis of the image fusion based on wavelet transform. It compares three kinds of image fusion methods （simple image fusion, image fusion based on tower decomposition, image fusion based on wavelet transformation） on left and right wall of adit. Experimental results show that the application of wavelet transformation in image fusion is practical, effective, and it has a practical value and a good application prospects tbr wavelet transform in digital image fusion.
