Hi,
I have a webcam that records 12 different diodes that glow in 3 different colors. The problem I want to solve is to check if the diodes are glowing or not. My idea is to have a reference image of when they are glowing and check if the live image is the same as the reference.
Don't really know what to do.. Do anyone have any ideas?

Imaq functions:
Extract Color plane (intensity) - of both reference and real-time
Subtract
Threshold
Find Circles (or Particle filter and Particle analysis if LED is not circle) -
GetColorPixelValue in orignal image at particle location - determine color
You can run vision assistant - it will help you build alogortihm and can create subVI for you
If LED locations are fixed, you need just Get Color Pixel Value VI and threshold values
