I am doing some OpenCV python code and I have below code at the end: if cv2.waitKey(1) & 0xFF == ord('q'): break So whenever I press q, the code breaks which is working fine. But below code is not working: if cv2.waitKey(1) & 0xFF == ord('q'): break if cv2.wait...
cv2.waitKey Where: delay=1000/frameRate# ms (The actual framerate would be lower due to the recognition time etc.) ... There could be reduction of the number of transactions also if you can check repetitive profiles and do not insert them twice in a batch (if t...
Additionally, the project addresses the need for user interaction and replaces the usage of cv2.waitKey with jcv2.waitKey. For instance, jcv2.waitKey(1000) waits for a button press for one second. By bridging the gap between OpenCV and Jupyter, the "OpenCV Jupyter UI" project enhances ...

The core logic of our script. Then we will call this function in a loop and display the current prediction image until we detect that theqkey is pressed on the keyboard. # Main loop; infers sequentially until you press "q" while 1: # On "q" keypress, exit if(cv2.waitKey(1) == ...
