OpenCV – Remove the background in your camera feed 🎦

Hi !

Yesterday I share 10 lines of code to adddress this very simple scenario:

Load and image and remove the background.

Today I’ll add a few extra lines, and I’ll remove the background from my camera feed. It’s fun to see how the Captain America shield was included in the cropped polygon 😁

And the sample code:

	#resize office to 640x480
	img = cv2.resize(img, (320, 240))
	green = (0, 255, 0)
	imgNoBg = segmentor.removeBG(img, green, threshold=0.50)
	# show both images
	cv2.imshow('office',img)
	cv2.imshow('office no bg',imgNoBg)
	if cv2.waitKey(1) & 0xFF == ord('q'):
	break
	# close camera
	cap.release()
	cv2.destroyAllWindows()
