Flip
The flip functions will flip the image from top-to-bottom (vertically), or from left-to-right (horizontally).
Crop
If a rectangular region of interest (bounding box) is defined, the image will be cropped to the region of interest. If no region is defined, the image will be unchanged.
Rotate
The rotate functions will rotate the image by 90 degrees in either the clockwise or counter-clockwise direction.
