Since it suits your needs, please accept this as the solution.

Basically what you should do is

• Grab the webcam frame
• Make a deep clone of the frame two times, one clone_frame and one original_frame, this can be done with the Mat.clone() function.
• Apply detection on both frame and clone_frame, but with different detection algorithms
• Now visualize all detections on original_frame

Does this suit your needs?
