    • Systems and methods are provided for generating unique signatures for digital video files to locate video sequences within a video file comprising calculating a frame signature for each frame of a first video; and for a second video: calculating a frame signature for each frame of the second video for corresponding first video frame signatures, calculating a frame distance between each of the corresponding video frame signatures, determining video signature similarity between the videos, and searching within a video signature similarity curve to determine a maximum corresponding to the first video within the second video. The method further applies area augmentation to the video signature similarity curve to determine a maximum from among a plurality of maxima corresponding to the first video file within the second video file.
    • 系统和方法被提供用于产生用于数字视频文件的唯一签名以定位视频文件内的视频序列,包括计算第一视频的每个帧的帧签名; 并且对于第二视频:为相应的第一视频帧签名计算第二视频的每帧的帧签名,计算每个相应视频帧签名之间的帧距离,确定视频之间的视频签名相似性以及在视频内搜索 签名相似性曲线以确定与第二视频内的第一视频相对应的最大值。 该方法还将区域增加应用于视频签名相似性曲线,以确定与第二视频文件内的第一视频文件相对应的多个最大值中的最大值。

    • The present disclosure relates to systems and methods for modeling, recognizing, and tracking object images in video files. In one embodiment, a video file, which includes a plurality of frames, is received. An image of an object is extracted from a particular frame in the video file, and a subsequent image is also extracted from a subsequent frame. A similarity value is then calculated between the extracted images from the particular frame and subsequent frame. If the calculated similarity value exceeds a predetermined similarity threshold, the extracted object images are assigned to an object group. The object group is used to generate an object model associated with images in the group, wherein the model is comprised of image features extracted from optimal object images in the object group. Optimal images from the group are also used for comparison to other object models for purposes of identifying images.
    • 本公开涉及用于在视频文件中建模,识别和跟踪对象图像的系统和方法。 在一个实施例中,接收包括多个帧的视频文件。 从视频文件中的特定帧提取对象的图像,并且还从后续帧中提取后续图像。 然后在从特定帧和随后帧的提取的图像之间计算相似度值。 如果所计算的相似度值超过预定的相似性阈值,则将所提取的对象图像分配给对象组。 对象组用于生成与组中的图像相关联的对象模型,其中模型包括从对象组中的最佳对象图像提取的图像特征。 为了识别图像,该组的最佳图像也用于与其他对象模型进行比较。
