State-of-the-art remotely sensed images-based change detection methods

Abstract

Change detection from satellite images provides scientific foundations for natural resource management, disaster mitigation, ecological environmental protection and sustainable development. Change detection based on optical remote sensing image has become an important research area in the field of remote sensing. Over the past 40 years, scholars worldwide have developed many methods on remote sensing image-based change detection. This paper attempts to review and analyze the research progress made in change detection from the perspectives of the key problems, methods, challenges and application areas. The research achievements made in the past 40 years are summarized based on the publications both internationally and in China; the state-of-the-art change detection methods is analyzed; and furthermore new research initiatives for the future research innovation are proposed. 地理实体或现象的变化数据是自然资源管理、灾害监测、生态环境保护和可持续发展等的重要科学分析依据。光学遥感影像变化检测是遥感科学与技术的重要研究领域，40年来，国内外学者针对遥感影像变化检测做了大量研究工作，取得了一系列成果。力图从变化检测关键问题、方法与技术、面临的挑战以及应用领域等多个角度对光学遥感影像变化检测研究进行系统的回顾，分析变化检测技术的研究现状，并且提出未来有待进一步解决的研究问题。
