Sequential patterns using pattern.selector #661

Closed Hima-Mehta closed 7 years ago

Hima-Mehta commented 7 years ago

Is it possible to present patterns(images) sequentially from list of generators using pattern.selector()? I am looking for direction preferences for a particular set of frames which were originally videos having objects moving in some direction.

Anything like that is definitely possible, but I'm not sure precisely what you need. It sounds like a case where I would set Selector.index to numbergen.ScaledTime(factor=1.0), so that whenever the time increases by 1, the index goes up by 1.

But for computing direction preferences, I'd normally use FeatureMapper to coordinate all this, not a Selector.

Okay, that was helpful! Thank you.
