| 中文摘要:针对传统的IHS变换图像融合方法在处理高分辨率图像和多光谱图像融合时出现的光谱退化现象的不足，对已有的传统和改进的IHS图像融合算法进行研究，提出一种新的基于IHS变换的像素级多次融合的方法框架，我们在将IHS变换后匹配得到的I分量和高分辨率图像之间的替换策略进行改进，采用两种或者多种互补的像素级图像融合算法进行图像的多次融合得到新的I’分量，然后采用IHS逆变换获得最后的融合图像，同时实现了传统IHS变换融合和SWT变换融合，根据主观判定和客观评价指标对融合结果进行评价。实验仿真结果，本文方法在融合质量以及视觉效果上都有相当不错的提高。 |

| Abstract:Aiming at the shortage of the spectral degradation phenomenon occurring in the process of dealing with the fusion of the high-definition picture and the multispectral image by the traditional image fusion method of IHS transformation, this paper studied the existing IHS image fusion algorithm and the modified one, and then put forward a new pixel multiple fusion method based on IHS transformation. This method improves the replacement policy between the I' component and the high-definition picture gained following IHS transformation, adopts two or multiple complementary pixel image fusion algorithms to get the new I' component, and then adopts IHS inverse transformation to get the final blending image. This paper also evaluated the fusion's results according to the subjective judgment and objective evaluation index. The results of simulation test show that, compared with the traditional IHS method and the SWT transform fusion method, this method makes the fusion quality and the visual effect gain a quiet great improvement. |
