Abstract

Many papers have reviewed remote sensing image segmentation (RSIS) algorithms currently. Those existing surveys are insufficiently exhaustive to sort out the various RSIS methods, it is impossible to comprehensively compare characteristics of different RSIS methods. In addition, the segmentation efficiency and accuracy of the RSIS methods cannot always meet the subsequent image analysis requirements. Thus, a clear comparative analysis of various RSIS methods is essential to provide an in-depth understanding of RSIS and theoretical ideas for conducting in-depth research in the future. The goal of this article is to provide readers with the latest information on optical RSIS technology. Comparative measures of these methods are provided in terms of conceptual details, the merits and demerits, and the performance of various RSIS methods. Moreover, various RSIS methods’ experiments are carried out on optical images using the NWPU VHR-10 public remote sensing datasets. Through the review of optical RSIS methods, this paper provides data as complete as possible for further related research and development of RSIS methods.

RÉSUMÉ

De nombreux articles ont passé en revue les algorithmes de segmentation d’images en télédétection (RSIS). Ces études sont insuffisamment exhaustives pour trier les différentes méthodes RSIS, il est impossible de comparer leurs diverses caractéristiques. De plus, l’efficacité et l’exactitude des méthodes de segmentation ne peuvent pas toujours répondre aux exigences requises pour le traitement subséquent des images. Ainsi, une analyse comparative claire des diverses méthodes RSIS est essentielle pour fournir une compréhension approfondie de ces méthodes et des idées théoriques pour développer de nouvelles approches à l’avenir. L’objectif de cet article est de fournir aux lecteurs les dernières informations sur la technologie optique RSIS. Les concepts des différentes méthodes sont analysés en détail, leurs avantages, leurs désavantages ainsi que leur performance sont comparés. En outre, diverses méthodes RSIS ont été testées sur des images optiques de la base de données de télédétection publiques NWPU VHR-10. Grâce à l’examen des méthodes optiques RSIS, cet article fournit des informations aussi complètes que cela est possible pour le développement ultérieur des méthodes RSIS.
