Abstract: 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 method. The overall classification accuracy and Kappa coefficient of CS-based method are higher than the See5.0 decision-tree one. The results demonstrate that the practicability of applying CS algorithm to classify the remote-sensing images.
