Hi there

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?

Thanks in advance.
