摘要:
该文提出用分数阶样条小波和Intensity-Hue-Saturation(IHS)变换结合的方法进行高分辨率全色图像和低分辨率多光谱图像的融合。分数阶样条小波由于具有良好的分数阶逼近性能,在分解图像时可得到更多的细节,而IHS变换在处理图像时会扭曲光谱特性,通过两者的结合,可得到高分辨率、多光谱图像。将该方法和传统‘Daubechies3’小波与IHS变换相结合的方法比较,实验结果证明了分数阶样条小波更多地保留了高分辨率图像的空间特性和低分辨率图像的光谱特性。
Abstract:
An image fusion technique based on fractional spline wavelets and Intenisity-Hue-Saturation ( IHS) transform is proposed for merging the high-resolution panchromat ic and low-resolut ion multispectral images. Fractional spline wavelets can obtain more information of image due to its fractional order of approximation when decomposing the image. IHS transform can distort the spectral characteristics of the original multispectral image. Combing the two methods can obtain high spatial and spectral resolut ion image. Comparing with the traditional -Daubechies 3. wevelet. s combinat ion with IHS trausform, the new method in this paper can perserve both spatial information of the high resolution image and spat ial information of the low resolution image.
