I'm working on the idea of recognizing a small video sequence (a sequence of 18 seconds) within a long one (a sequence of 15 minutes), the first idea that comes to mind stats that I have to characterize this small video with some kind of identification.
So I will use the identification to look at this small sequence inside the long sequence.
I'm asking this question to the community, to share with me an approach that can help me characterize this small video, then recognize it within the long sequence.
