摘要
针对退化图像空间分辨率较低的问题,提出了一种基于均方能量的多分辨率图像融合方法。首先对图像进行二层小波变换,然后根据所得到的高频小波系数的统计特征来定义均方能量,并以此作为图像融合测度来对退化图像进行多分辨率特征融合。试验结果表明,融合后的图像在保留细节信息和光谱信息上均能获得较好的效果。
Aiming at the shortcomings of low spatial resolution in degenerative image,a degenerative image fusion method based on the mean square energy is proposed in this paper. Firstly two-layer wavelet transform is used to handle image. Secondly the mean square energy is defined by statistical feature of high frequency wavelet factors. It takes the mean square energy as measure of feature selection to carry out degenerative images fusion. The experiments show that the fused images obtain better results in terms of both preserving spectral information and spatial information of the degenerative images.
