Resumen:
In this paper two classes of methods for computing optical flow from a sequence of images oriented to the self-identification of motion in subaquatic vehicles is presented. Correlation and differential methods are analyzed and compared under the criteria of precision, computational cost and robustness against continuity in the frame sequence. For motion tracking a forgetting factor is applied. Two case studies are analyzed corresponding to the external motion of a rigid body and the ego-motion of a moving vehicle in a synthetic sea bottom.
