  author={Nuno R. Gracias},
The underwater environment poses a difficult challenge for autonomous vehicle navigation. Common positioning solutions require the deployment of precisely located acoustic beacons, which typically implies high operating costs. Vision sensing is increasingly being regarded as a low cost alternative, but is limited to short range due to visibility and lighting factors. However, it can provide precise positioning if an adequate representation of the environment is found. Video mosaicing presents… CONTINUE READING
