- wongarsu 2y agoThose are pretty standard. A standard YOLO training run applies more transformations than that, and there are ready-made modules that do the same in keras and pytorch (for their mobilenet and VGG16). I'm not sure if anyone is training any serious vision algorithm without that kind of data augmentation. What I am talking about is that they want to recognize scenes containing the images, but only have the images as training data. They have a good idea what those scenes will look like. Going there to take actual training pictures was evidently not viable, but generating approximations of them might have been.
