Data Augmentation Question

[EmirhanToprak]

Hi sir, i checked your survey about data augmentation and it citation to [31] and i also checked that survey but i couldn't quite understand the augmentation.
If you don't mind, can you upload image one random and one 4 corner 1 center for example?
Is the 4 corner and 1 center about, divide the image near from the center to 4? And the random one is select 4 random points and create one augmanted image?
