Abstract: The invention is a method for converting a monoscopic video movie passively acquired using a single camera to a stereoscopic video movie. The method comprises generating stereoscopic pairs comprising, for each frame in the original sequence, a transformed original frame selected from the monoscopic video movie and a transformed alternate frame. The transformed frames are generated from the original and the alternate frame.

Abstract: In accordance with the invention, a golf ball is marked with two equatorial O-rings adjacent an equator of the ball and equally spaced therefrom, which are in a golfer's full view of the top side of the ball when the ball is accurately aligned to its desired initial starting line and a golfer is properly positioned to putt. The polar regions of the ball are also imprinted with a pattern which is essentially invisible to the golfer when properly positioned to putt. When the ball is aligned to a particular starting direction, and properly struck precisely and squarely and rolls purely in that starting direction, the equatorial O-rings will roll without wobble, and the polar O-rings will remain essentially invisible to the golfer. But when side spin is imparted to the ball at impact, the equatorial O-rings (circumferential lines) will appear to wobble as the ball rolls, and the polar O-rings will become periodically visible and emphasize the appearance of wobble.

Abstract: A golf training mat for practicing short game shots includes a ball striking surface having markings associated with foot and ball positioning. The mat also includes a first position marking having a front foot marking, a tear foot marking and a ball marking. The front foot marking and the rear foot marking are positioned along an alignment axis, wherein the ball marking is positioned substantially between the front foot marking and the rear foot marking along a line substantially perpendicular to the alignment axis. The golf training mat also includes a second position marking having a front foot marking, a rear foot marking and a ball marking. The front foot marking and the rear foot marking are positioned along an alignment axis, wherein the ball marking is positioned substantially in line with the front foot marking along a line substantially perpendicular to the alignment axis.

Abstract: A set of golf club wedges each having a club face (10) is disclosed wherein the lofts of the individual clubs progressively increases. The hitting surface of each club head may take the form of an insert (12) that includes a series of grooves, the design of which is varied from club to club to provide increasing friction with loft. As a result, a golfer can impart the same amount of spin to a golf ball with each of the wedges despite a substantial difference in loft and club head swing speed between the respective clubs. In addition, the surface roughness of the hitting surface may also be increased as loft increases to further control the spin imparted to the ball.
