基于布谷鸟算法的遥感影像智能分类

提出了一种新的基于布谷鸟算法的智能式遥感分类方法。采用布谷鸟智能优化算法，自动搜索遥感影像各波段的最优阈值分割点，并定义各波段最优阈值分割点和影像分类目标类别的连线为布谷鸟的最佳解，构造以If-Then形式表达的遥感分类规则。将所提的基于布谷鸟算法的影像分类方法应用于ALOS影像分类中，并与蜂群智能遥感分类方法和See5.0决策树方法进行了对比分析。结果表明，布谷鸟智能遥感分类的总体精度和Kappa系数均比蜂群智能遥感分类和See5.0决策树方法更高，该智能遥感分类方法具有更好的分类效果。

Intelligent Remote Sensing Classification Based on Cuckoo Search Algorithm

A new,intelligent approach to classify remote-sensing images based on Cuckoo search algorithm is presented.Cuckoo search algorithm,a new bio-inspired intelligence algorithm,is widely used to solve optimization problems.Cuckoo search algorithm to search for the optimal upper and lower threshold values on each band of remote-sensing image is applied.The classification rules are constructed by the links between the optimal split values and classification type in the explicit formation of'if-then',and each link corresponds to the optimal solution of one Cuckoo,nest or egg.By taking an example of ALOS image in the north shore of the Yangtze River estuary,the proposed classification method based on CS algorithm is implemented and tested against See5.0 decision-tree mnethod.The overall classification accuracy and Kappa coefficient of CS-based method are higher than the SeeS.0 decision-tree one.The results demonstrate that the practicability of applying CS algorithm to classify the remote-sensing images.
