Automatic water bodies extraction model based on K-T transformation
基于K-T变换的地表水体信息遥感自动提取模型

Threshold method and spectral relationship method are traditional methods for water body information extraction,the two methods,however,could not distinguish cloud shadow from water body,which leads to lower precision.For achieving a optimal model,the K-T transformation(Kauth-Thomas transformation)was applied to the TM image firstly,and then the improved model of water bodies extraction was found using the six new wave bands of the TM image after K-T transformation.It can be concluded that only when the spe...
