apply the same correction across multiple frames/images #83

Open grigorisg9gr opened 9 years ago

grigorisg9gr commented 9 years ago

Mostly for editing in videos, but also when the fitting has made a consistent mistake across multiple images.

The idea is to correct a landmark in one frame and then choose the number of the upcoming frames that the same correction will be applied.

In my head, this kind of behaviour should go in a separate video sequence mode. Otherwise it might be a bit confusing.

I think the interface for this should be something like an 'onion' effect, where you can see the other frames with a specified alpha, similar to how keyframe editing is done in video editing software. That way, you can better see how many frames ahead you want to apply the change to. Maybe only applying the alpha to inside the convex hull of the landmarks or something, to make it easier to see how the hulls are changing across the sequence.

@lirsacc has added a 'Copy Previous' button to the UI (and keyboard shortcut) that provides some amount of functionality like this without going down the full brown video editing mode.

I like @patricksnape 's idea for how such a feature may work in a future video specific mode in the landmarker, but support for this is a major job that isn't pressing right now.
