摘要
图像融合的目的是把同一目标的多幅图像融合成一幅质量高的图像。本文给出了一种基于小波变换的图像融合方法,首先对两幅图像使用正交小波进行分解,得到两幅图像的小波分解系数,根据小波系数的特点,对两幅图像的小波系数进行比较,取绝对值大的小波系数构成融合的小波系数矩阵。对融合小波系数矩阵进行小波反变换,得到两幅图像的融合图像。最后使用该方法对两幅图像进行了融合,得到的融合图像汲取了两幅图像的优势,是一幅质量高的图像。
The goal of image fusion is to combine a high-quality image from multi-image about the same object. The paper presents an image fusion scheme based on wavelet transform. Firstly, the two images are decomposed by orthogonal wavelet, the image＇s wavelet coefficients are got. Comparing with the two image＇s wavelet coefficients,wavelet coefficients＇ matrix is composed of maximum absolute value, the fused image is obtained by the inverse wavelet transform. The last section of the paper verifies the method by experiment and gets the good experimental results.
