摘要
图像融合是一种重要的增强图像信息的技术方法 ,如何对同一目标的多源遥感图像数据进行有效的融合 ,最大限度地利用多源遥感数据中的有用信息 ,提高系统的正确识别、判断和决策能力 ,这是遥感数据融合研究的重要内容之一。提出了一种基于小波变换的融合方法 ,使得融合图像在最大限度保留多波段光谱信息的同时 ,提高了清晰度和空间分辨率。并对实验结果运用 MATLAB语言进行了仿真 ,从几个方面对结果做了深入的分析与对比 ,取得了良好的效果。
Image fusion is one of the important techniques to enhance image information of remote sensing. How to make efficient data fusion for multi-source remote sensing image of the same object, make the best of the useful information, improve the system's ability of correct recognition, judgement and decision, is an important aspect of data fusion research. This paper introduces one image data fusion method based on wavelet transformation. In the fusion image, all the multi-spectral characteristics have been preserved, and the definition and the spatial quality of multi-spectral image have been improved. The results were fully analyzed and discussed. Satisfactory effect has been obtained while applying MATLAB language to analyze the result of the experiments.
