Abstract: Optical flow refers to the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. Optical flow algorithms can be used to detect and delineate independently moving objects, even in the presence of camera motion. The present invention uses optical-flow algorithms to detect and remove marine snow particles from live video. Portions of an image scene which are identified as marine snow are reconstructed in a manner intended to reveal underwater scenery which had been occluded by the marine snow. Pixel locations within the regions of marine snow are replaced with new pixel values that are determined based on either historical data for each pixel or a mathematical operation, such as one which uses data from neighboring pixels.

Abstract: A navigation guidance system utilizes an electronic compass to determine a desired linear travel path between two way points and to monitor a direction of travel of a user. The system then determines if the direction of travel is within an established tolerance. If the system determines that the direction of travel is outside of the established tolerance, the system alerts the user through one or more alert indicator components. The alert indicator component can emit a visual alert, an audible alert, a tactile alert, or any other suitable method for informing the user accordingly. The alert can be a simple alert or of varying degrees to inform the user of the magnitude of deviation from the desired travel path. The navigation guidance system can be integrated into a carrying device, such as a pair of goggles, swim goggles, glasses, sunglasses, a helmet, a mountable enclosure, etc.

Abstract: A panoramic-view diving mask with self-sealing, non-glued, removable watertight lenses. The lenses are self-sealed by an assembly process in which a layer of elastic gasket medium is applied or attached to either one or both beveled contacting edges of the frontal and side lenses, with the non-contacting edges having a lip so as to provide an enhanced seal between the lens and the frame. The lenses are assembled by pressing an assembly ring against the frontal lens and side lens simultaneously, forcing compression against the elastic gasket medium at the contacting edges of the two lenses and securing both lenses to the mask frame. The result is a watertight seal, achieved without adhesives, at the contacting edges of the front and side lenses. This process reduces storage space, packaging size and transporting costs during mass production.
