Fast knowledge based recognition of harbor target
基于知识的快速港口识别

A recognition method of harbor target in large gray remote sense image was presented. Distributed inherit characters were analyzed according to the knowledge of harbor targets. Two methods of extracting the candidate region of harbor were designed in accordance with different sizes of the harbors. Thresholds were used to segment the land and the sea with strategies of controlling the segmenting error. Finally, harbor recognition was implemented according to its inherent character (half close region of seawater).
