由于技术、算法和方法的不断增加，遥感变化检测的最新评论变得越来越复杂和不同。为了提供一个更清晰的，概括性的视野，本综述组织了文献的分析单位和比较方法，用于识别变化。这大大减少了以前的审查中存在的概念重叠，提供了一个简洁的术语来理解和应用变更检测工作流程。在这个框架下，几十年的研究已经总结了当前的变化检测方法的概述。确定并描述了七个分析单元和六种比较方法，突出了变化检测工作流程中每种方法的优点和局限性。其中，像素和分类后更改方法仍然是最受欢迎的选择。在这篇评论中，我们扩展了以前的摘要，并提供了一个可访问的字段的描述。这通过在分析单元和变化分类方法之间放置明确的分离来支持未来的研究。这种分离，然后讨论，应用变化检测研究和未来的基准测试实验提供指导。
State of the art reviews of remote sensing change detection are becoming increasingly complicated and disparate due to an ever growing list of techniques, algorithms and methods. To provide a clearer, synoptic view of the field this review has organised the literature by the unit of analysis and the comparison method used to identify change. This significantly reduces the conceptual overlap present in previous reviews giving a succinct nomenclature with which to understand and apply change detection workflows. Under this framework, several decades of research have been summarised to provide an overview of current change detection approaches. Seven units of analysis and six comparison methods were identified and described highlighting the advantages and limitations of each within a change detection workflow. Of these, the pixel and post-classification change methods remain the most popular choices. In this review we extend previous summaries and provide an accessible description of the field. This supports future research by placing a clear separation between the analysis unit and the change classification method. This separation is then discussed, providing guidance for applied change detection research and future benchmarking experiments.
