Automatic obstacle detection is a key feature for unmanned surface vehicles (USV) operating in a fully autonomous manner. While there are currently many approaches to obstacle detection in maritime environments (e.g., LiDAR, radar) the proposed approach resorts to standard, inexpensive RGB cameras to perform the detection of such obstacles. Recent advances in deep neural network detectors achieve state-of-theart detection results, and some one-stage networks achieve very good results while maintaining inference times small enough to be compatible with real-time capabilities on low-cost embedded processing units. In this paper, we train the YOLO v4 network to detect different types of ships, using publicly available maritime datasets. After training, we evaluate the obtained network on the processing unit located onboard the UAV with respect to detection accuracy and real-time processing capability, thus demonstrating that the presented detection method can be considered a robust, fast, flexible, and inexpensive approach to obstacle detection in USV applications.

Digital services enable users to interact with a broad range of applications and, as such, have become an essential part of our daily lives. Although convenient, their ubiquity comes at a significant cost in energy, raising sustainability concerns. We access these services by triggering a computing continuum, spanning from the device to the edge, fog, and cloud. Scheduling decisions made at each layer impact the overall quality of service (QoS) and energy consumption of digital services.

Accurate and real-time instance segmentation on mobile devices enables a wide spectrum of applications such as augmented reality, context-aware inspection and environmental cognition. However, the computation resource demanded by instance segmentation impedes its deployment on resource-constrained commercial mobile devices. Prior studies enable smartphones to conduct computational-intensive tasks in real-time with the assistance of an edge server. However, simply applying an edge-assisted framework hardly achieves delightful segmentation performance due to the movements of devices and targets, pixel-level precision requirements, and huge computational overhead even for edge nodes. This work proposes edgeIS, an edge-assisted system that enables real-time and accurate instance segmentation on mobile devices. edgeIS embraces the mobile device sensing ability of surroundings and its own motion, and redesigns an innovative mobile-edge collaboration paradigm suitable for segmentation tasks. We implement edgeIS on a lightweight edge node and different mobile devices. Extensive experiments are conducted under four datasets. The results show that edgeIS can run on mobile devices in real-time and achieve a 0.92 segmentation IoU, outperforming existing state-of-the-art solutions. We further embed edgeIS in an AR-based inspection system deployed in an oil field and the performance of edgeIS meets the demand of the industrial scenario.
