A speed-up seed point otsu method for ship detection in various scenarios

The technology of specific target detection and recognition in Synthetic Aperture Radar (SAR) image is one of the most important issues especially in the area of remote sensing observation. Aiming at ship detection in complex scenario, this paper presents a universal framework and a novel method called Speed-up Seed point OTSU (SSOTSU) based on OTSU and invoked in the framework. Different from the classic OTSU method, SSOTSU obtains seed points and compute threshold in specific area around every seed point. The experiment results demonstrate that our method can be implemented to detect ships under complicated scenario of both SAR images and optical images fast and obtain high accuracy in detection.
