Special Issue Information

Dear Colleagues,

Intelligent Unmanned Vehicles (IUVs), in the form of either Unmanned Ground Vehicles (UGVs), Unmanned Aerial Vehicles (UAVs) or Unmanned Underwater Vehicles (UUVs), have emerged as potential tools to assist humans in various missions, such as environment sensing, space exploration, rescue, surveillance, inspection, real-time monitoring, remote sensing, etc. The IUV-related technologies have been continuously evolving, attracting a vast number of research works with an exponentially growing number of applications. The UGVs/UAVs/UUVs with on-board sensors and/or hyperspectral systems can sense the environment and/or capture spectral image data, which are then fed into an AI model for evaluation and prediction. Although numerous applications, algorithms and commercial tools have been developed for UGVs, UAVs and UUVs, there are challenges and open issues in modelling, analyses and practical design that need to be addressed. This Special Issue aims to provide a comprehensive overview of state-of-the-art technologies of IUVs in practical systems for image capturing and sensing.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Channel modelling and communication protocols of IUVs (UAVs/UGVs/UUVs);
  • Energy consumption modelling of IUV sensing devices;
  • Resource allocation for IUV communications;
  • Security of IUV communications;
  • Analytical frameworks of IUV communications;
  • Machine learning for IUV communications and sensing;
  • On-board data processing for image capturing and sensing on IUVs;
  • Experiment and prototype of IUVs for image capturing and sensing;
  • Object detection, classification and segmentation algorithms for multispectral and hyperspectral imaging;
  • Feature extraction and reduction for multispectral and hyperspectral imaging;
  • Change and anomaly detection in multispectral and hyperspectral images;
  • Interpretability and explainability in machine learning for multispectral and hyperspectral imaging;
  • Applications of multispectral and hyperspectral imaging;
  • Deployment of multispectral and hyperspectral classification and segmentation techniques in hardware-constrained environments;
  • Data fusion from multiple sensors.

We look forward to receiving your contributions.

The image transmission over wireless media experiences not only unavailable performance loss caused by the environment and hardware issues, but also information leakage to eavesdroppers who can overhear and attempt to recover the images. This paper proposes a secure cooperative relaying (SCR) protocol for the image communications in wireless relay networks (WRNs) where Alice sends high-resolution (HR) images to Bob with the assistance of a relaying user named Relay, and in the presence of an eavesdropper named Eve. In order to enhance the security of the image communications, random linear network coding (RLNC) is employed at both Alice and Relay to conceal the original images from Eve with RLNC coefficient matrices and reference images in the shared image datastore. Furthermore, the original HR images are downscaled at Alice to save transmission bandwidth and image super-resolution (ISR) is adopted at Bob due to its capability to recover the HR images from their low-resolution (LR) version, while still maintaining the image quality. In the proposed SCR protocol, Bob can decode both the original images transmitted from Alice over the direct link and the images forwarded by Relay over the relaying links. Simulation results show that the SCR protocol achieves a considerably higher performance at Bob than at Eve since Eve does not know the coefficient matrices and reference images used at Alice and Relay for the RLNC. The SCR protocol is also shown to outperform the counterpart secure direct transmission protocol without the relaying links and secure relaying transmission without the direct link. Additionally, an increased scaling factor can save the transmission bandwidth for a slight change in the image quality. Moreover, the impacts of direct, relaying and wiretap links are evaluated, verifying the effectiveness of the SCR protocol with the employment of Relay to assist the image communications between Alice and Bob in the WRNs.
