Results on different parts of algorithm. Each line represents different value of minimum interval value (--min-scenecut command line parameter).
It can be seen that performance of the algorithm on difficult youtube videos is worse than on documental films from BBC.

Here is the code for testing

F score can be calculated using formula below:
Alt Text
where Precision and Recall are:
Alt Text
tp is number of correctly detected scene changes
tn is number of correctly detected frames without scene changes
fp is number of false alarms
fn is number of missed scene changes

The average speed for the algorithm:
Part FPS
4K videos 2.5
BBC Dataset 238
Other videos 30

Dependency of F score and speed on resolution
