“…In these studies, the surveillance area was restricted to the coastal regions and the combination of data from AIS, SAR, IR, video and radar was used in the fusion process to obtain the vessel tracks. Furthermore, there are some other works that focused on the fusion of both sensor and non-sensor data (Andler et al, 2009;Ding, Kannappan, Benameur, Kirubarajan, & Farooq, 2003;Fooladvandi et al, 2009;Lefebvre & Helleur, 2004;Mano, Georgé, & Gleizes, 2010;Riveiro & Falkman, 2009).
