Pixel Count in ROI

[jbelim]

Hi guys,

I've looked at the Particle Analysis Report Example VI the comes with the evaluation version of Labview 8.5. I want to modify the VI such that instead of showing the number of pixels at the side, it show in the picture itself, like the Particle Analysis example. Can I do it in Labview and not using Vision? What functions and controls do I need to add to the program so that I can do the pixel count? I'm pretty new to this so help is greatly appreciated. Thank you!

Hi jbelim,

You can add text to image by using the IMAQ Overlay Text.vi. This VI is a part of the Vision Development Module and does need to be purchased separately.

If you need the information that the Particle Analysis Report Example shows you, use the IMAQ Particle Analysis Report.vi. This VI returns an output cluster that you can parse and overlay using the IMAQ Overlay Text.vi.
