| titleOfInvention | SAR image ship target segmentation method |
| abstract | The invention discloses a SAR image ship target segmentation method, and relates to an SAR image ship target segmentation method. The invention aims to solve the problems of unsatisfactory segmentation caused by insufficient prior information, excessively strong side lobes and trailing, excessively close distance between two ships and the like when the ship target is segmented by the existing method. The specific process is as follows: carrying out water-land separation based on colors and regions on an original image; performing Otsu binary segmentation and region segmentation on the image after water and land separation to obtain the size of the ship; setting a background window based on the size of the ship, estimating K-distribution parameters to obtain a threshold value on the assumption that clutter in the background window is K-distribution, and segmenting a ship target based on the threshold value; fourthly, carrying out opening operation on the ship target to obtain a segmented image; the method is used for the field of ship target segmentation. |
