Image (pixels) processing using labVIEW

[yangq]

Hi all,

I am new to the image processing of labVIEW and have some questions about it:( ..I hope you can help me:)

For CCD camera testing, I will get a image from a camera and all the pixels almost have the same brightness. However I need the labVIEW program to find out the most uniform pixels area (maybe 100*100 pixels, and those pixels have the most close brigthtness level) and store the coordinates of this area. How can I implement this requirement in labVIEW? The picture should be load into the labVIEW program and be process, instead of capture by the real-time camera.

Thanks for you help 🙂

Best regards,

Aries 🙂

If I were you, I would start with the NI Vision Assistant - this will allow you to easily load in images (either from file or direct from a camera) and allow you to try applying various image processing operations and measurements (e.g. threshold with a low tolerance?) to get the result that you need - you can then export this sequence into LabVIEW.

You will need the NI Vision toolkit installed.

You can also probably do the image processing yourself by converting the image to an array of pixels and writing your own algorithm to find the region of interest.
