摘要： Techniques for determining if two video signals match by extracting features from a first and second video signal, and cross-correlating the features thereby providing a cross-correlation score at each of a number of time lags, and finally determining the similarity score based on both the cross-correlation scores.
摘要翻译： 用于通过从第一和第二视频信号中提取特征来确定两个视频信号是否相匹配的技术，并且对特征进行交叉相关，从而在多个时间滞后的每一个处提供互相关分数，并且最终基于两者确定相似性得分 互相关分数。

摘要： Techniques for determining if two video signals match by extracting features from a first and second video signal, and cross-correlating the features thereby providing a cross-correlation score at each of a number of time lags, then determining a mean magnitude of a difference of average values at each of the lags, and finally determining the similarity score based on both the cross-correlation scores and the mean magnitude difference scores, and optionally then outputting an indication of a degree of match between the first and second video signals.
