In order to detect man-made objects in underwater video, we propose and validate a novel method based on background subtraction methods. The other main contribution is the introduction of a priori elements deduced from positioning sensors. These elements allow to enhance the visibility of underwater objects thanks to the calculation of the sun position in(More)
An optimized technique based on the fringe-adjusted JTC (joint transform correlator) architecture is proposed and validated for rotation invariant recognition and tracking of a target in an unknown input scene. To enhance the robustness of the proposed technique, we used a three-step optimization by: (1) utilizing the fringe-adjusted filter (H FAF) in the(More)
