Haar cascade tracking of multiple balls

Question

I created haar cascade which is able to track all balls in the image, then I tried to train it to track only green balls but its not working. Is it even possible to track only balls with certain color?

Answer 1

Haar features are only based on pixels intensity . That's why the input image is converted to a grayscale image before being processed (as shown in this Python tutorial ).

So the answer is no , you can't track only balls of certain color with an Haar Cascade Classifier.

Instead, you could try the approach explained here .
