Aiming at the adversary features of infrared ship image under sea-sky background such as low contrast between targets and background and fuzzy image edges,an ROI extraction method is proposed.The algorithm preprocesses and enhances the image in frequency domain,and extracts target ROI near the sea-sky-line by multi-grade segmentation and fusion.Experimental results show that this method can overcome the shortcomings in conventional segmentation methods.The results of multi-grade segmentation and fusion can extract the target regions,thus lay a good foundation for later target recognition and tracking.
