基于IHS变换的直方图配准影像融合

IHS Transform-based Histogram Matching Images Fusion

提出了基于直方图配准基础上的高分辨率影像融合．以QUICKBIRD全色0．6 m分辨率影像为准,对IKONOS多光谱4 m分辨影像进行几何配准,裁剪出相同区域的影像．对IKONOS影像进行IHS变化,以变化后的I成份影像灰度直方图为准,对QUICKBIRD影像灰度直方图进行配准．将IKONOS多光谱影像的H、S成份和配准后的QUICKBIRD全色影像进行逆IHS变化融合．实例结果表明经过直方图配准后的影像融合更清晰,融合效果更好．

This paper presents IHS transform-based histogram matching fusion spatial high-resolution images. Geometrical coregistration QUICKBIRD 0.6-m panchromatic image and IKONOS 4-m multi-spectral images, clipped out same region. 1HS transform IKONOS images, according to the intensity component gray histogram to match QUICKBIRD gray histogram. Inverse- IHS fusion of IKONOS hue and saturation component with QUICKBIRD Panchromatic Image is matched. The study shows that IHS transform-based histogram matching fusion images is clearer, including more egicient fusion.
