ok so I've been looking into this for a while now, and keep getting confused. A little bit of background on what I am trying to do: I have a live feed coming in from a firewire camer and would like the user to be able to create a rectangle roi over the feed (anywhere over its viewing screen) and have it show on a coresponding plot the linear averages. I know this should be really simple, I do have the vision software package but am getting confused on how to start this. Any suggestions, examples, help would be much appreciatted. Thank you!
