Hi I'm trying to devide Color using IMAQ Colorlean.vi
It has Color Spectrum indicator then that has 1D Array which has 16 element(when set color sensitivity = low )
so i want to know what is the standard to devide color spectrum 16 element?
and what is each element 0~16 standard color?
EX) 1D Array Index 14 mean black
15 mean white
Solved! Go to Solution.

I'm not sure what you mean, maybe post what you have?
I'd convert to HSL and do a threshold (or 2, min and max, being careful, because H is a circular scale (the max value is R IIRC, so is the min value)) on the H channel.
That will instantly select pixels based on color, and it will be (way) faster then a learning algorithm.

I have test program for color spectrum.
This program divide color spectrum in ROI.
If you move ROI, color spectrum will change.
Color Spectrum has 16 element 1D array
then i found 8 element Color.
my destination is found that 16 element Color

Do you get more colors if you set Color Sensitivity to medium or high?
If you convert the ROI to HSL and do a histogram, you could do any number of color subdivision you want. More importantly, you'd actually be in control over what you're doing.
A few caveats though:
H will be messed up if L is low.
H is cyclic, so the min H 'connects' to max H.

Here is a documentation that explains how the color spectrum is divided depending on the sensitivity:
https://www.ni.com/docs/en-US/bundle/ni-vision-concepts-help/page/color_spectrum.html
Regarding which color is represented by which element of the spectrum array, I couldn't find more info than what you already have.

thanks to your response
i already saw that page.
but that page doesn't have every element..
i want to know what criteria for divide color and represent color
i'm still try to find that

HI thanks to your response.
color spectrum has diffrent number of element when set Color Sensitivity to Low or medium or high.
low - 16 element
medium - 30 element
high - 58 element
I will try to do with your advice thanks

your anser was what i find.
thank you so much but i already find that example named color matching.vi
then there doesn't have that color image what you upload..
is that color matching.vi?
this is color mathching.vi in my Labview 2018 example.
