I’m reading through the threshold documentation, and I’m trying to figure out where I pull these values:(l\_lo, l\_hi, a\_lo, a\_hi, b\_lo, b\_hi) from on the live histogram? Does this grouping map to (red low, red high, green low, green high, blue low, blue high)? if not where do I get these values for color tracking? I’ve attached an image of what I’m trying to track 🙂

thank you!

Hi, switch the drop down box to LAB. We don’t track colors in the RGB color space.

Also, see the Tools-\>Machine Vision-\>Threshold Editor. This is easier to use.
