Perhaps a bit of a broad question, but I have a sequence of pictures from which I want to create either a colour spectrum or overall RGB score to identify changes in the picture sequences (i.e. change of object). I was wondering if it's possible to do anything along these lines without having the Vision toolkit?
This is coming from the following problem:
* moving transporter belt
* want to be able to track change in colour and match big/small objects whilst they appear under the camera
* compare previous with current pictures to measure
1) when they come in the frame and when they leave the frame
2) what their size is (i.e. small or large)
3) what colour they are
I was thinking that having a some sort of aggregated RGB score or colour spectrum would do the trick?
Can be rough, doesn't need to be superb accurate

Hi Ta,
do you already know this example:
.../National Instruments/LabVIEW 2011/examples/lvoop/BoardTesting/Read_Me.html
It's about a fictional quality check in terms of printed circuit boards which are moved on a conveyor belt. No Vision used.
The Vision toolkit can be used both for image acquisition and image processing.
I recommend Vision for image acquisition.
