OpenRTVSE

Hello, OpenRTVSE is an Open Real-time Video Search Engine based on video fingerprint.
In screenshots, you can see the trails of video fingerprints.
Conceptually each video snapshot has it's own characteristic which contains the average RGB colors of snapshot pieces. And fingerprint has the differences among some series of snapshots as well.
I want this source might be a good example for learning video or it's fingerprint.
I try to make it simple as long as I can.
Let's talk about fingerprint and it's algorithms.
