title: How can I grab frame only when there is plant/flower featured frame in the real time camera vision?
body: <p>The camera is fitted in front of the bot. I want to classify two plants. Now there will be other objects too, in front of the bot. Now instead of processing every frame from the video, I want to just grab a frame of only the plant and then try to classify the plant. The idea is to just avoid processing the other objects (non-plants).</p>
  <p>For Example: Is it possible to use Canny Edge Detection(or any other method) to vaguely understand the features of (plants/flowers) and later grab that frame to classify(for this I am using VGG16)??</p>
