Summary: This paper discusses the challenges of using infrared remote sensing images in real-world applications, including time-consuming preprocessing, decreased contrast, and difficulty in discriminating low-resolution targets. To address these challenges, a progressive task-based universal network is proposed, which includes a stripe denoising component, an object detection component, and a feedback loss adjustment mechanism. Experimental results demonstrate that the proposed method outperforms other state-of-the-art methods in infrared image ship detection.

Summary: Monitoring and identifying ships in remote sensing images is crucial for various applications, but ship detection remains challenging due to small size and complex backgrounds. In this paper, we propose a few-shot multi-class ship detection algorithm with attention feature map and multi-relation detector (AFMR) to address this problem. The proposed method achieves good detection performance on publicly available datasets and a self-constructed dataset.

Summary: Change detection in remote sensing images has a significant impact on various applications. Recent advances have been made in change detection methods for different ground objects, but there are still limitations in feature recognition, resulting in unclear boundaries and a need for improved accuracy. To address these issues, the use of HRNet and new data augmentation methods are introduced to enhance accuracy. Additionally, the integration of CSWin and HRNet models improves performance, and a feature fusion network named A-FPN is designed to enhance perception of ground objects at different scales.

Summary: Automatic detection and localization of objects in remote sensing images are important for remote sensing systems. However, existing frameworks usually suffer from poor performance due to a lack of large-scale training datasets. To address this, a novel sensor-related image synthesis framework called RS-ISP is developed. It introduces designs to ensure distribution consistency between generated and real images, resulting in improved ship detection performance.

Summary: Traditional methods of on-orbit geometric calibration using ground control points or stars as references for geostationary cameras face challenges in collecting high-precision GCPs due to cloud cover and extraction algorithms. In response, a novel approach using the relative motion of stars is proposed to improve positioning accuracy, overcoming the limitations of cloud cover and the number of observed stars.
