Data augmentation requires that darknet be built with support for OpenCV.
Some notes from AlexeyAB:
From page 6 of the YOLOv4 paper:
Mosaic represents a new data augmentation method that mixes 4 training images. Thus 4 different contexts are mixed, while CutMix mixes only 2 input images. This allows detection of objects outside their normal context. In addition, batch normalization calculates activation statistics from 4 different images on each layer. This significantly reduces the need for a large mini-batch size.
Images are randomly flipped left-right. Turn this off if you are training classes that depend on left-hand and right-hand distinctions.
For example, training to recognize the letters "b" and "d", or "left hand" and "right hand" would be problematic if flip is enabled.

Data augmentation may combine multiple images into a single image ("mosaic").
