Hello,

I'm trying to repeat one example and i can't find this elementt . It's something like a bounding box.

Best regards

It might help if you tell us which example you're tying to repeat.

Imaq Rake Example

If you double click the VI, it should open. In VI Info (CTRL+I) or Save As... would reveal it's path. It's a sub VI of the example, so I'd expect it in a sub directory of the example, or maybe a facilitation directory for all IMAQ examples.

This example on the textbook page. So it 's problem.

Ah, that explains the grayscale image...

I think it simply grows the bounding boxes.

So a Add with a -3,-3,3,3 cluster constant would probably do the same. Or -[1,-1,1,1]X3. Then simply create a subVI from that.

Edit: never mind

What's the textbook about? Does it include a CD or DVD, for example? How old is it?

(Strange code: There is no need for the FOR loop at the bottom, that unbundle could be placed in the last FOR loop.)

About digital image processing and machine vision. Published 2007. Yea it include a DVD but i don't have it.

That (old) version of IMAQ Rake returns an array of points, whereas IMAQ Overlay Oval accepts a Rectangle, so my guess is that the VI creates a rectangle (square) 3 pixels either side of the point.

Input: [5,15]

Output: [2,12,8,18]

or similar.

It's certainly not a built-in VI, anyway.
