    • 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.
    • 提供了一种系统和使用方法,用于产生对旋转,拉伸,缩放,翻转和其他仿射变换鲁棒的视频指纹。 系统和方法基于确定目标视频图像的感兴趣点和存储在数据库中的图像的集合。 还通过将目标视频图像的指纹与数据库中的图像的指纹进行比较来提供识别复制的视频图像的方法。 视频指纹识别的方法包括:从视频图像中定义感兴趣的点,确定包含所述兴趣点的定向边界区域,所述区域已经被用于产生定向边界区域的相同变换所变换,并且通过对 兴趣为格雷码,使相似的图像具有较小的汉明距离,不相似的图像具有较大的汉明距离。 感兴趣点的识别由许多技术提供,包括分割,识别仿射协变区域和尺度不变特征。

    • Methods, systems, and computer program products, including computer programs encoded on a computer readable storage medium, for providing content to a user based on the mode of the user. A method includes: providing a data structure that includes query logs; processing query logs to determine candidate queries that satisfy a criteria, the processing including determining a location of interest, if any, for each query log entry and where the criteria requires an entry to have been submitted from a location that is different from a location of interest associated with the entry; evaluating the candidate queries to determine targeting information for the location of interest; receiving a request for content from a user that is proximate to the location of interest or has expressed an interest in the location of interest; and providing content to the user based at least in part on the targeting information.
