Recognizing a plant in a pinch
When asked to assist how to quickly recognize a plant with a webcam I remembered an Apple WWDC presentation called "Find my iCone" an app that tracked an orange construction pylon using it's color.
I already had some web/Javascript code to do some chromakey (greenscreen) swapping, so I just re-purposed it. However, tracking the correct color of say "purple flowers" needed to be a little less fined grained then #ef0114 (for example, I have no idea what "color" that is by looking at it's hex values), so I grabbed a JS library to print colors as words.
Here's the code:
<!DOCTYPE html>
<h1>I don't see anything.
