A new region growing based method for ship detection in high-resolution SAR images

High-resolution SAR are of great value in remote sensing nowadays. To make good use of the characteristics of high-resolution SAR images to detect targets, we present here a region growing method. First, we calculate a threshold according to the given PFA to pick up bright pixels as the seeds. Second, we define the criteria which is mainly based on the relationship between pixels in a high-resolution SAR image and then execute the growing process. Finally, we exclude false alarms according to some geometry features. The experiments and results show that it is a constructive and effective way using region growing algorithm to detect ships in high-resolution SAR images.
