摘要
探讨了混沌系统在遥感影像置乱中的应用,并对传统的Logistic混沌模型进行改进。将Logistic混沌模型、混合光学双稳模型和改进的Logistic混沌模型应用于遥感影像置乱中,并对这三种模型的算法特性及在遥感影像中应用的性能进行了分析和比较。结果表明混合光学双稳模型的性能最佳,为最安全的混沌加密算法。
This paper discusses the application of chaotic system to remote sensing images scrambling and improves the traditional Logistic chaotic model. Logistic, MOB （Mixed Optical Bi-stability） and improved Logistic chaotic models are applied to remote sensing image scrambling, which analyzes and compares three algorithms performances and its application to remote sensing image. The experimental results show that MOB model has the best performance and it is the safest chaotic encrypt algorithm.
