Can you give an example of where that happens?

In some cases it can be better if face detection fails in certain images but it manages to track it in videos (as initialization is based on previous frames).

I set the det_parameters.multi_view = true, it make same.

TadasBaltrusaitis commented 6 years ago

Even with det_parameters.multi_view = true, there is a chance that videos will be more accurate because of the tracking.

Do you have any specific examples of where this happens?
