autothreshold value

[nadiah]

Hi. 

Currently, I'm doing an image processing using IMAQ Vision (LabVIEW 2010) to inspect corrosion in pipeline.

I successfully detect the corroded area by using IMAQ AutoBThreshold 2. May I know where I can find the exact value of the threshold used in the function?

In my report, I need to state the threshold value to strenghten my result.

Thank you.

Hello,

you can determine the threshold values with "Threshold Range Out" using "IMAQ AutoBThreshold 2 VI".

Please see the attached code - the output "Threshold Range Out" is used for manual thresholding and it produces the same results.

If you run the example without modification, the values from 88-255 produce white regions (1 or 255 in this case) and values from 0-87 black regions (0). So, your threshold vlaue in this case is 88 (88 inculded).

I hope this helps.

Best regards,

Yup. I got it. Thanks Klemen!
