Possibility to add a counter on the webcam object detection and tracker

[ajr82]

Hi, this is great! The Yolo object detection and tracker on a webcam feed could be very useful on live microscopy camera video feeds.
Would it be however be possible to add a live counter on the live video feed? For example, if I only wanted to detect one class, on a webcam, could I add a counter to the video feed or in a separate description field below the video feed that counts the number of detected objects in real-time?
And if this is possible would I be able to generate and display a ratio between the number of two classes in real time?

Thank you!
