Sažetak
As an important part of modern marine monitoring systems, ship target identification has important significance inmaintaining marine rights and monitoring maritime traffic. With the development of artificial intelligence technology, image detection and recognition based on deep learning methods have become the most popular and practical method. Inthis paper, two deep learning algorithms, the Mask R-CNN algorithm and the Faster R-CNN algorithm, are used to buildship target feature extraction and recognition models based on deep convolutional neural networks. The established modelswere compared and analyzed to verify the feasibility of target detection algorithms. In this study, 5748 remote sensingmaps were selected as the dataset for experiments, and two algorithms were used to classify and extract warships andcivilian ships. Experiments showed that for the accuracy of ship identification, Mask R-CNN and Faster R-CNN reached95.21% and 92.76%, respectively. These results demonstrated that the Mask R-CNN algorithm achieves pixel-levelsegmentation. Compared with the Faster R-CNN algorithm, the obtained target detection effect is more accurate, and theperformance in target detection and classification is better, which reflects the great advantage of pixel-level recognition.
