The availability of multi-sensor and multi-resolution images obtained through earth observation satellites has given rise to a greater need for fusion technology. Fusion can provide comprehensive information about a particular scene or area by bringing the information of two or more images into a single plane. The technique has been in use for the past three decades, and several methodologies have been introduced in the literature. However, with the invention of new sensors and technology, the number of challenges has increased. While several review and survey papers have explored different aspects of fusion, this paper provides a comprehensive discussion of the tools available and the implications of their use for the fusion of remote sensing images. Tools based on multi-resolution analysis (MRA) and multi-geometric analysis (MGA) are widely used in the field of image fusion. We provide a detailed study of MRA- and MGA-based tools, their effectiveness, and the impacts of the corresponding fusion schema in retaining the desired information.

遥感影像融合中使用的多分辨率分析 (MRA) 和多几何分析 (MGA) 工具综述

通过对地观测卫星获得的多传感器和多分辨率图像的可用性对融合技术产生了更大的需求。Fusion 可以通过将两个或多个图像的信息整合到一个平面中来提供有关特定场景或区域的全面信息。该技术在过去的三年中一直在使用，并且文献中已经介绍了几种方法。然而，随着新传感器和技术的发明，挑战的数量增加了。虽然几篇评论和调查论文探讨了融合的不同方面，但本文对可用工具及其使用对遥感图像融合的影响进行了全面讨论。基于多分辨率分析（MRA）和多几何分析（MGA）的工具广泛应用于图像融合领域。我们详细研究了基于 MRA 和 MGA 的工具、它们的有效性以及相应融合模式在保留所需信息方面的影响。
