Multiple OpenCV instances?
Mar 29th, 2009, 7:11am  
Is there a way to run multiple instances of opencv in one sketch? I want to detect eyes within detected faces, however creating a new opencv instance with the same parent again overwrites the previous one. Omitting the parent "this" from the instance creating doesn't help either.
Grateful for any help!

From my experience you can't run multiple instances of openCV and use both to capture video.  I believe the webcam can only be used by one object at a time to read video.  If you want to then use that video in multiple ways you can use the copy() function to a new instance of openCV.

For what you want to do, you want to use the ROI function.  That targets the openCV object to search within a certain area.
