摘要
A method is performed at a computing system having one or more processors and memory. The method includes receiving a first video clip having three or more image frames and computing a first hash pattern, including: (i) computing a temporal sequence of differential frames and (ii) for each differential frame: identifying a respective plurality of feature points and computing a respective hash value that represents spatial positioning of the respective feature points with respect to each other. The method includes receiving a second video clip having three or more image frames and computing a second hash pattern by applying steps (i) and (ii) to the three or more image frames. The method includes computing a distance between the first hash pattern and the second hash pattern and determining that the first and second video clips match when the computed distance is less than a threshold distance.
