Abstract：This paper do some research about the small moving target under the background of sea level, in the process of target detection, this thesis proposes morphological filtering and edge detection algorithms. First, convet the collected images to gray images and then do it with Top-Hat transform, To remove noise of the process of transformation, we do on the median filter on the transformed image.finally we detect the target with the edge detection of Sobel operator . It confirmed that the two combined method can detect the target well and also eliminate smearing and noise to some extent. At last,we do some smear treatment.
