In general, you’ll want to preserve the images’ aspect ratio when using cv2 resize — especially if these images are presented as output to the user. Exceptions most certainly do apply, though. As we explore machine learning/deep learning techniques, we’ll find that our internal algorithms ...
A single image can have multiple targets. Every target must be enclosed in a bounding box. The bounding boxes are color coded. To create the bounding box in the images, click on the “Create Box” button, to create a bounding box. After the box is drawn, go to the “Label List” co...
