With either of these approaches, you'll have a binary image. Adjust the threshold or other factors until this isolates the targets. Note that when viewing a binary image, be sure to right-click on the image viewer and choose the palette for binary.\
Thanks for this tip, I didn't even think of the lit vs unlit. I think a combination of the two will be the best way to go, The white inner tubes mimic the reflective tape, so you need to use the color threshold to tell the difference. However if you're just doing it in autonomous the lit vs unlit should suffice.
