主 题:Convolutional Neural Network(CNN) Synthetic Aperture Radar(SAR) inshore ship detection hybrid features high-energy point number amplitude spectrum
摘 要:Convolutional Neural Networks(CNNs)have recently attracted much attention in the ship detection from Synthetic Aperture Radar(SAR)***,compared with optical images,SAR ones are hard to ***,due to the high similarity between the man-made targets near shore and inshore ships,the classical methods are unable to achieve effective detection of inshore *** mitigate the influence of onshore ship-like objects,this paper proposes an inshore ship detection method in SAR images by using hybrid ***,the sea-land segmentation is applied in the pre-processing to exclude obvious land regions from SAR ***,a CNN model is designed to extract deep features for identifying potential ship targets in both inshore and offshore *** this basis,the high-energy point number of amplitude spectrum is further introduced as an important and delicate feature to suppress false alarms ***,to verify the effectiveness of the proposed method,numerical and comparative studies are carried out in experiments on Sentinel-1 SAR images.
