The demos of face_recognition, dnn_face_recognition and people_detect use test/face_detector_withface_test_diamondback.mp4 of opencv_apps (the trained faces, and the whole bodies of the people for HOG), and the demos of qrcode_detection, barcode_detection, aruco_detection and dnn_text_detection use test/codes.mp4 and test/text.mp4 of opencv_apps, made by test/make_codes_video.py and test/make_text_video.py. The tests of the nodes use the videos in test/.
