A Fast Method to Spot a Video Sequence within a Live Stream

Abstract — This paper presents a novel algorithm to spot a known video sequence within a live video stream. The algorithm is split into two branches, a branch to create a digital signature out of the video sequence in question, and another is to search for this sequence within a live video stream. The algorithm is categorized to consume low processing power and satisfy real-time requirements. Thus, this allows the algorithm to search for not only one video sequence, but more, and not only within one video stream but more, resulting in a many-to-many relationship. Both branches of the proposed algorithm are based on selecting key frames, processing these frames, and performing a number of comparisons that involve luminance image parameters.
