I have a few questions about what way should I choose for develop an
real time video analysis app. I already have a solid knowledge of
image analysis and objetive c aswell. The basic idea to start with
this is an app that get a real time video signal and pass a set of
filters (thresholding, segmentation) that count or discount an
object (e.a Beans) and shows the number of the current count.
Im not really sure what core video offers, but as fair i understand
while reading the guide, Do i need to think something like the next
workflow?
iSight Signal - Core Video - Buffer - vImage (convolutions to each
frame?) - Core Video (Compose an output video with a eliptical
color around the bean?) - Results?
My understanding is that Core Video is primarily intended for
processing video to be displayed on screen. You should probably take a
look at the OpenCV computer vision library - it's much better suited
to this sort of image analysis.
