Did you have a look at this function?

Hi.

 I am sorry. I did. I did many projects on NI vision assistant.

i shud get hue value of Red apple range 0 - 20 after selecting ROI. 

I extracted HSI plane then applied histigram. But results are not matching.

As per my alogortithm Plane is different from Hue value.

Thank you

Why don't you use the Histrogram directly at the color image with the HSL Model?

Here i have attached my code. I did up to ROI perfectly.

Then i converted to HSI image. 

From HSI i want hue value. And it should be 0-20 for red apple.

and 25 to 50 for yellow apple.

Give me any hits.
