We also discussed how to divide an image into smaller patches and some applications around it. This is the replacement of cv2.imshow for jupyter. The best way to show a grid of images in the Jupyter notebook is probably using matplotlib to create the grid, since you can also plot images on matplotlib axes using imshow. import cv2 When it comes to deep learning-based object detection there are three primary object detection methods that youll likely encounter: Faster R-CNNs (Ren et al., 2015); You Only Look Once (YOLO) (Redmon et al., 2015) Single Shot Detectors (SSDs) (Liu et al., 2015) Faster R-CNNs are likely the most heard of method for object detection using deep learning; however, 6.
