how to implement the push notification after convert.

Question

I want to let my console app to use the push notification in UWP, so my team decide to covert our Console app to UWP. The question is how to implement the push notification after convert.

            ret, frame = cap.read()
            if not ret:
                break
            # Resize the frame to reduce latency
            frame = cv2.resize(frame, (640, 480))
            # Run face detection asynchronously
            faces = await detect_faces(session, frame)
            # Draw face rectangles
            if faces:
                for face in faces:
                    rect = face['faceRectangle']
                    cv2.rectangle(frame, (rect['left'], rect['top']),
                                  (rect['left'] + rect['width'], rect['top'] + rect['height']),
                                  (0, 255, 0), 2)
            cv2.imshow('Frame', frame)
            if cv2.waitKey(1) & 0xFF == ord('q'):
                break
    cap.release()
    cv2.destroyAllWindows()
# RTSP stream URL
rtsp_url = "rtsp://your-stream-url"
# Run the stream processing
asyncio.run(process_stream(rtsp_url))

The above implementation is a kind of solution that will provide a good balance between accuracy and reduced latency for processing RTSP streams with Azure Face API using Python. Adjusting the frame size, rate, and leveraging asynchronous processing will help mitigate latency issues.

Lastly, Optimization Strategies

Deploy edge computing solutions to preprocess and filter frames before sending them to the cloud.

If the latency is still high, consider sending frames in batches to reduce the number of API calls.

Process multiple RTSP streams in parallel using multithreading or multiprocessing, depending on your hardware capabilities.
