superslug Posted August 8, 2011 Report Share Posted August 8, 2011 Hello all, I am working on a project with NI Vision and I need to single out moving traffic, I was wondering if anyone had any idea's they could share. I was thinking of using the new optical flow algorithms in 2010 and looking at the results it seems like the optical flow HS VI would be a good place to start however it's output are "a reference to the image that contains the horizontal component or the magnitude component of the computed velocity at each pixel." and also one for the vertical component. I do not not know what this means though. Are they saying that each pixel value is the velocity value or is the data stored in the image some other way? thanks, Bernard Quote Link to comment
