RyanLee HI @erik I have a question about edge_detector example in depthai-python. Our user hope to use RGB(Color) video not only for edge detection but also dispaly its rgb video(without modification like edge detection) at the same time. Is it possible for them? here is the link for edge detection from depthai-python. https://github.com/luxonis/depthai-python/blob/main/examples/EdgeDetector/edge_detector.py Best regards, Ryan.
