Opening an image in OpenCV is as simple as using the cv2.imread() function, in which inside this function you provide the path to the image you want to display. Let's say that we have the following image of a tropical tree shown at the following link: Tropical Tree. To load and ...
while ways of displaying OpenCV image (in cv::Mat format) on the local development machine has been discussed in the articleAdd Plotting Support For OpenCV C++, it's also noticeably important to be able to display the image from the front-end of a Jupyter notebook, which opens the possibil...

As per our documentation, you should be able to obtain the image array by accessing the .img attribute or an equivalent method provided by the track function. Once you have the numpy array of the frame, you can then pass it to cv2.imshow() to display it. Do not forget to handle the...
