title: is there a non AI way of classifying images into two groups in Python?
body: <p>I'm in the process of developing a parking app and need a way of classifying images of parking signs in the UK into their two colour types, yellow and white.</p>
  <p>I've tried a number of methods in openCv and the reliability that I've found just isn't robust enough.</p>
  <p><a href="https://i.stack.imgur.com/cY9UL.png" rel="nofollow noreferrer">White parking Sign</a></p>
  <p><a href="https://i.stack.imgur.com/naZ15.jpg" rel="nofollow noreferrer">Yellow parking sign</a></p>
  <p>Alternatively, is there a quick/lightweight way of training an AI to classify these quickly,</p>
  <p>thanks guys</p>
