I don't understand their arguments:

`* example:
 * example_tracking_multitracker Bolt/img/%04d.jpg
 * example_tracking_multitracker faceocc2.webm KCF`

Which is it, just an image or a video and a algorithm. The above seems to specify you can do both. And if just an image, how would that work with tracking? Bit confused.

Also - which one is the best ?

both variants point to a video sequence.

VideoCapture has a hidden feature, if you give it a string Bolt/img/%04d.jpg, it will try to load an image sequence like

Bolt/img/00001.jpg
Bolt/img/00002.jpg
Bolt/img/00003.jpg
Bolt/img/00004.jpg

So that is assuming i would have 00001.jpg - 4.jpg in my directory ? And then what would it do with it ? Sorry to be thick - is this if you had frames extracted from a video file ?
