Synthetic Aperture Radar (SAR) has the advantage of continuous observation throughout day and in all weather conditions, is used a wide range military civil applications. Among these, detection ships at sea an important research topic. Ships SAR images are characterized by dense alignment, arbitrary orientation multiple scales. The existing algorithms unable to solve these problems effectively. To address issues, A YOLOV8-based oriented ship classification method using imaging with...
The detection of ships encompasses an abundance applications within the domains fishery management, marine rescue operations, and maritime monitoring. In recent years, a multitude detectors based on deep learning have been utilized for purpose ship using synthetic aperture radar (SAR) images. However, disturbed by strong scattering background land influence SAR target scale, existing face great challenges in detecting inshore small ships. To solve this problem, article proposes oriented...
With the rapid development of intelligent technologies, deep learning-based object detection has been widely applied in dynamic fields, especially vehicle management. However, challenges accurate recognition and tracking remain, particularly due to issues like intra-class variations inter-class similarities re-identification across camera viewpoints. This paper proposes a method for long-range small target based on YOLOv8 algorithm, aiming improve accuracy performance targets complex...
Model-based decomposition methods are widely used in full-polarization synthetic aperture radar (SAR), for the inversion and interpretation of ground features constitute an important approach understanding behavior backscattering. However, owing to substantial differences between land marine environments, different man-made natural vegetation scattering structures render existing models unable reasonably characterize scatterers on ships. Moreover, combination polarization neural networks...
Polarimetric synthetic aperture radar (PolSAR) as an active microwave imaging device employing pulse compression technology to obtain echo information of multiple polarization channels has been widely used in marine target detection. However, the detection ship targets PolSAR images is often disturbed by clutter interference, such side lobes, ghost ships, etc. Additionally, current common convolutional neural network object models are accompanied a large number parameters, thereby, their...
Fine-grained ship classification in optical remote sensing images is a major challenge the ocean observation field, elaborated as follows: First, cost of acquiring expensive. Obtaining numerous labeled samples difficult, resulting poor generalization ability training models. Second, features target cannot be accurately obtained owing to complex background interference. Third, inter-class similarity and intra-class diversity among different ships render difficult. In this study, we propose...
