    • A method, system and computer-readable media for detecting scene changes in a video that includes providing by one or more computing devices a plurality of passes through the video where a plurality of detected scenes from a first pass in a conventional method are identified and a second pass through the detected scenes are provided by the computing device. A plurality of scene boundary differences corresponding to the detected scenes, a fixed average, and a varying average are computed by the computing device. The scene boundary difference is compared with the fixed average and the varying average and if the scene boundary difference is less than the fixed average and the varying average, the detected scenes are combined else the detected scene being an abrupt scene change is determined. The steps of computing a varying average to combining the detected scenes are repeated by the computing device.
    • 一种用于检测视频中的场景变化的方法,系统和计算机可读介质,所述方法,系统和计算机可读介质包括由一个或多个计算设备提供多个通过所述视频的多个通过,其中识别出常规方法中的第一遍的多个检测到的场景,以及 由计算装置提供第二次通过检测到的场景。 由计算装置计算与检测场景对应的多个场景边界差,固定平均值和变化平均值。 将场景边界差与固定平均值和变化平均值进行比较,并且如果场景边界差小于固定平均值和变化平均值,则检测到的场景被组合,则确定检测到的场景是突然场景变化。 通过计算装置重复计算变化的平均值以组合检测到的场景的步骤。

    • Biometric authentication technology, in which biometric data is maintained for a group of people. The biometric data includes sorted similarity scores, where each of the sorted similarity scores is computed to represent similarity between a corresponding biometric image and a reference image. A biometric verification system accesses a biometric image of at least a portion of a person, accesses the reference image, and computes a similarity score that represents similarity between the accessed biometric image and the reference image. The biometric verification system searches the sorted similarity scores included in the biometric data using the computed similarity score and outputs a result based on the searching.
    • 生物统计认证技术,其中为一群人维护生物特征数据。 生物特征数据包括排序的相似性分数,其中计算每个排序的相似性分数以表示对应的生物测定图像和参考图像之间的相似度。 生物特征验证系统访问人的至少一部分的生物图像,访问参考图像,并且计算表示所访问的生物统计图像和参考图像之间的相似度的相似度分数。 生物特征验证系统使用所计算的相似性得分来搜索生物特征数据中包含的排序相似性得分,并输出基于搜索的结果。
