摘　　要：针对多光谱和高分辨率全色影像的融合,本文对IHS、HSV、lαβ等几种常见的基于色彩变换的融合方法进行了详细的介绍。通过对融合影像光谱损失的分析,改进了基于IHS变换的融合方法;通过实验对两组影像融合效果进行了全面的分析对比。实验结果表明,该方法在提高融合影像空间分辨率的同时,能更好地保证影像的光谱质量。For the fusion of multi-spectral and high-resolution panchromatic images,several common methods based on color transformation,such as IHS,HSV,and lαβ,are introduced in detail.Based on the analysis of the spectral loss of the fused image,the improvement based on IHS is improved.An experiment including two sets of image is carried out and a comparative analysis is implemented.The experimental results show that the method can improve the spatial resolution of the fusion image,while maintaining better the spectral quality.
