measure mean value and stadard deviation for every segment

[igurov]

Dear all,

I want to measure the mean value and the standard deviation for each segment on the attached pciture ( for example for the number 8 i have 7 segments => i need 7 values). The problem is that I can figure it out how to do that. The only thing that I am able to achieve is to measure these two quantities for the whole picture using IMAQ Histogram but I don't know how to do that for each segment in the picture.

Thanks,

IG.

Hi

What exactly do you like to measure? Intensity of each segment of all numbers on your picture?

Do you have a grayscaled example picture?

First you can work with the Vision Assistant to figure out your steps, then compile it to LabVIEW code. 

So you need to set a coordinate system, then you can check for each segment the intensity.

You can also find a lot of tutorials and examples on our website or with the example finder in LabVIEW.

Kind regards
