摘要:
Large-scale matching of videos is performed by matching a set of probe videos against a set of reference videos to determine if they are visually and/or aurally similar. The visual and audio fingerprints of all probe videos and reference videos are divided into subfingerprints, which are divided into LSH bands. The LSH bands of the probe videos are sorted in one list, and the LSH bands of the reference videos are sorted in another list. Then, the two sorted lists are linearly scanned for matching LSH bands. The matching LSH bands are sorted by probe video ID, and each probe video ID is searched to find matches between probe videos and reference videos. Further, an incremental matching process identifies matches as groups of new probe videos and/or new reference videos are added, without unnecessary repetition of matching old probe videos against old reference videos.

A combined fingerprint is generated for a video that can match two near-identical videos that differ only in their aspect ratios or formats. A transformation strategy is selected by selecting a first and a second aspect correction method. A first transformed video is generated by applying the first aspect correction method to the video. A second transformed video is generated by applying the second aspect correction method to the video. A first fingerprint is generated using the first transformed video. A second fingerprint is generated using the second transformed video. The combined fingerprint is generated by combining the first half of the first fingerprint with the second half of the second fingerprint.
摘要:
A system and method of use are provided for generating video fingerprints that are robust to rotation, stretching, scaling, flipping and other affine transformations. The system and method are based on determining points of interest for a target video image and a collection of images stored in a database. A method of identifying a copied video image is also provided through comparison of the fingerprint of the target video image with fingerprints of images in a database. The method of video fingerprinting involves: defining points of interest from a video image, determining an oriented bounding area encompassing said points of interest that have been transformed by the same transformations used to produce the oriented bounding area and creating a fingerprint by encoding the points of interest as Gray Code such that similar images have a small Hamming distance and dissimilar images have a large Hamming distance. The identification of points of interest are provided by a number of techniques including segmentation, identification of affine covariant regions and scale invariant features.

An adjustable customized golf club, e.g., a golf putter, as well as a method for using the club, wherein the club has a head, a striking surface attachment, and one or more lock fittings that positively lock the striking surface attachment to the head. The striking surface attachment is one of several selectable attachments, each with different performance characteristics, e.g., rebound. The one or more lock fittings positively lock the striking surface attachments to the putter head such that the club components are firmly fixed, yet are still quickly removable and replaceable. One embodiment provides a golf club comprising a head defining at least one slot, and a replaceable striking surface attachment having protrusions compressed within the at least one slot.

An embodiment of the present invention provides an offset lacrosse head comprising a shaft, a collar, and a head. The collar defines an opening that receives the shaft. The head has a juncture. The juncture defines a socket that receives the collar, and the socket and the shaft are non-concentric. In a further aspect of this embodiment, the shaft has a shaft axis, the opening of the collar has an opening axis, the socket of the juncture has a socket axis, and at least one of the socket axis, the opening axis, and the shaft axis is offset, when viewed from a side elevation of the lacrosse stick facing an exterior of a sidewall of the head.

A lacrosse head having a soft mesh pocket with an area of its strings coated with stiffening material. The coated area defines, for example, a ball release area, a ball pocket, and/or a throwing channel. One embodiment provides a lacrosse head pocket that includes a continuous piece of mesh, and a stiffening material coating a first area of the mesh, with a second area of the mesh being uncoated. The first area defines, for example, a ball release area, a ball pocket, and/or a throwing channel.

A lacrosse head having a wide catching area and channeled thongs. One embodiment includes a stop member, a left sidewall connected to the stop member, a right sidewall connected to the stop member, and a scoop connecting the left sidewall to the right sidewall opposite the stop member. The scoop is disposed about 25.5 cm from the stop member. The widest point of lacrosse head is in a catching section disposed from about 6 cm to about 17 cm from the stop member. The left sidewall is convex with respect to the interior area of the head at a portion of the left sidewall between the widest point and the scoop. The right sidewall is convex at a portion of the right sidewall between the widest point and the scoop. In another embodiment, the sidewalls rise from the plane of the scoop and include thong holes to provide channeled thongs.
