Local complexity of image is first calculated in this algorithm  and then the original image is preprocessed with different de noising methods according to local complexity  finally the image is binarized based on local complexity and the target is segmented. The experiment results indicate that the algorithm is adaptive and can meet the requirements of real-time processing  which lays a foundation for ship target detection under complex background. 2010 IEEE.
