摘要: 本文探讨了一种基于影像直方图匹配的Brovey融合法(IHM Brovey)。该方法解决了Brovey融合法限制多光谱波段数量,以及融合影像色彩亮度和地物光谱特性变异大的缺陷。试验表明,相比Brovey融合影像,IHM Brovey融合影像的各波段平均相关系数降低了2.60%,平均信息熵提高了0.25%,平均梯度提高了6.02%,更好地保留了原多光谱影像的丰富光谱信息和全色影像的精细地物空间纹理信息;IHM Brovey融合影像中水体、林地、建筑物等地物的光谱偏移量大幅降低,尤其是针对试验区整景遥感影像的光谱偏移量低至0.46%,影像融合前后的地物光谱变异更小,稳定性更好。

Abstract: The paper discusses a Brovey fusion method based on image histogram matching(IHM Brovey fusion). This method solves the defects of Brovey fusion method limiting the number of multi-spectral bands and large variation of spectral characteristics of ground objects in fusion image results. The experimental results show that compared with Brovey fusion image, the average correlation coefficient between each band of IHM Brovey fusion image is reduced by 2.60%, the average information entropy is increased by 0.25%, and the average gradient is increased by 6.02%, which better preserves the rich spectral information of the original multi-spectral image and the fine spatial texture information of panchromatic image. It is found that the spectral offset of surface objects such as water, forest land and buildings in the fusion image results of this method is greatly reduced, especially for the whole remote sensing image of the test area, the spectral offset is as low as 0.46%, and the spectral variation of surface objects in the fusion image of IHM Brovey method is smaller and more stable.
