	abstract = {<p>The increasing demand for underwater robotic intervention systems around the world in several application domains requires more versatile and inexpensive systems. By using a wireless communication system, supervised semi-autonomous robots have freedom of movement and, at the same time, allows the operator to get camera feedback and supervise the intervention. Moreover, the limited and varying bandwidth of underwater radio frequency (RF) and underwater acoustic modem channels is a major obstacle. This paper proposes the use of progressive (embedded) image compression and region of interest (ROI) for the design of an underwater image sensor to be installed in an Autonomous Underwater Vehicle, specially when there are constraints on the available bandwidth, allowing a more agile data exchange between the vehicle and a human operator supervising the underwater intervention.</p>

	abstract = {<p>Autonomous manipulation in real underwater environments presents many unexpected situations, such as lack of visibility due to light reflections or presence of particles in the water. Moreover, the use of cameras is still very important, considering that they provide a natural sensor input to the operator, and many robust and efficient underwater manipulation algorithms have been implemented using this kind of sensor. Moreover, underwater applications, especially the ones that may involve interacting with artificial structures like panels, or even with other robots, would be very much improved if the umbilical cable could be substituted by a wireless system, improving so mobility. In that sense, Radio Frequency connection, allowing the transmission of camera input to the operator, would be a potential improvement. The present article describes the system implemented at the TRITON project (www.irs.uji.es/triton) in order to localize a robot arm related to a panel with a valve and a connector, using sonar and radiofrequency techniques, in order to experiment autonomous manipulation under lack of visibility conditions. Moreover, the Radio Frequency system enables the transmission of camera monitoring information at small distances, which has previously been compressed using specific techniques.</p>
