Special Issue Information

Dear Colleagues,

Recently, intelligent agents have rapidly grown in remote sensing with their autonomy, flexibility, and a broad range of application domains. A variety of intelligent agents with autonomous navigation capabilities have been developed for different remote sensing application scenarios, such as Unmanned Ground Vehicle, Maritime Autonomous Surface Ship, Unmanned Aerial Vehicle, and Planetary Lander et.al. With the development of remote sensing technology, the performance of sensors carried by intelligent agents is becoming more and more powerful. Advanced remote sensing image offers a range of beneficial data for the application of intelligent agents with high spectral, temporal, and spatial resolution, as well as accurate and reliable environment information in a wide range of scenes. This provides the necessary data guarantee for the agent to complete complex missions in the field of remote sensing.

Obstacle detection and avoidance are fundamental problems for intelligent agents because they must detect and avoid obstacles in their environment according to the collected information. However, remote sensing images have the characteristics of large scenes, small targets, and complex backgrounds, which makes it challenging to quickly and intelligently detect long-distance obstacles and make reasonable avoidance strategies in remote sensing images. Moreover, the adaptability of agents still needs to be improved for addressing the obstacle detection and avoidance problem in complex scenarios, including unfamiliar environments, unknown obstacles, and dynamic scenes. The current development of artificial intelligence technology provides an intelligent solution paradigm for many visual perception and decision-making problems. The performance of obstacle detection and avoidance would be advanced by the inclusion of Artificial Intelligence techniques in the design of remote sensing applications.

This Special Issue aims to take advantage of the cutting-aged artificial intelligence technology, developing intelligence obstacle detection methods with strong adaptability and a high degree of autonomy. The research papers will provide readers of Remote Sensing with a wide range of remote sensing image understanding, obstacle detection and avoidance, and advanced artificial intelligence technology with theoretical research and practical methods.

To highlight new solutions of AI algorithms for obstacle detection and avoidance in remote sensing images, manuscript submissions are encouraged from a broad range of related topics, which may include but are not limited to the following activities:

  • Artificial Intelligence Approaches for Remote Sensing Image Understanding;
  • Artificial Intelligence Approaches for Obstacle Detection and Avoidance;
  • Obstacle Adaptive Perception and Learning Approach in Dynamic Scenes;
  • Autonomous Navigation and Obstacle Avoidance Based on Remote Sensing Images;
  • Data-driven Application for Obstacle Detection and Avoidance;
  • Detection of unseen or merely seen obstacles;
  • Weakly/semi-supervised detection approaches for Obstacle Detection and Avoidance;
  • Obstacle detection based on image saliency and camouflage cues.

Learned image compression has achieved a series of breakthroughs for nature images, but there is little literature focusing on high-resolution remote sensing image (HRRSI) datasets. This paper focuses on designing a learned lossy image compression framework for compressing HRRSIs. Considering the local and non-local redundancy contained in HRRSI, a mixed hyperprior network is designed to explore both the local and non-local redundancy in order to improve the accuracy of entropy estimation. In detail, a transformer-based hyperprior and a CNN-based hyperprior are fused for entropy estimation. Furthermore, to reduce the mismatch between training and testing, a three-stage training strategy is introduced to refine the network. In this training strategy, the entire network is first trained, and then some sub-networks are fixed while the others are trained. To evaluate the effectiveness of the proposed compression algorithm, the experiments are conducted on an HRRSI dataset. The results show that the proposed algorithm achieves comparable or better compression performance than some traditional and learned image compression algorithms, such as Joint Photographic Experts Group (JPEG) and JPEG2000. At a similar or lower bitrate, the proposed algorithm is about 2 dB higher than the PSNR value of JPEG2000. Full article

Semantic segmentation of very-high-resolution (VHR) remote sensing images plays an important role in the intelligent interpretation of remote sensing since it predicts pixel-level labels to the images. Although many semantic segmentation methods of VHR remote sensing images have emerged recently and achieved good results, it is still a challenging task because the objects of VHR remote sensing images show large intra-class and small inter-class variations, and their size varies in a large range. Therefore, we proposed a novel semantic segmentation framework for VHR remote sensing images, called Positioning Guidance Network (PGNet), which consists of the feature extractor, a positioning guiding module (PGM), and a self-multiscale collection module (SMCM). First, the PGM can extract long-range dependence and global context information with the help of the transformer architecture and effectively transfer them to each pyramid-level feature, thus effectively improving the segmentation effectiveness between different semantic objects. Secondly, the SMCM we designed can effectively extract multi-scale information and generate high-resolution feature maps with high-level semantic information, thus helping to segment objects in small and varying sizes. Without bells and whistles, the mIoU scores of the proposed PGNet on the iSAID dataset and ISPRS Vaihingn dataset are 1.49% and 2.40% higher than FactSeg, respectively. Full article
