– Sensors for environmental monitoring;
– Submarine robotics (AUV—autonomous underwater vehicles, ROV—remotely operated vehicles, etc.);
– Monitoring of sea geomorphology, maritime activities, and navigation using remote sensors (radar/optical/satellite instruments) mounted on satellites, coastal structures, flying platforms (aircraft–helicopters), and ships;
– Coastal oceanography, for the measurement of wave motion and coastal erosion and related sensors;
– Development of imaging techniques for underwater mapping, underwater archaeology, submarine research, and structural monitoring and inspections;
– Development of mathematical, hydro fluid dynamic models for oceanography and related sensors;
– Physical oceanographic and submarine geophysics;
– Marine biology and aquaculture;
– Marine meteorology and study of the sea–atmosphere interface;
– Climate changes and related monitoring;
– Study of the anthropic impact on the marine environment.
This relation derives from an approach that moves from so-called ocean engineering (the study of applied engineering techniques to the scientific disciplines inherent in seas and oceans) towards ICT requirements.
In our case, this Special Issue intends to investigate the reverse path, i.e., to exploit the techniques and the ICT approaches, and in particular the study and application of signal- and image-based methods, and to explore the advantages of their application to the areas mentioned above.
In particular, this Special Issue seeks original contributions that address and discuss the impact and relevance of signals and images treatment and processing in R&D areas such as:
– Oceanographic engineering;
– Sensor and marine monitoring;
– Marine robotics;
– Optical and acoustic image analysis;
– Virtual and augmented reality for sea investigation;
– Human–sea interaction.
In addition to the abovementioned topics, innovative and breakthrough contributions based on the convergence of signal and image processing, analysis, and understanding in any challenging sea application are welcome.
