WebTo augment data without damaging the message embedding, only rotating multiples of 90 or horizontally ﬂipping are used in steganalysis, which generates eight ﬁxed results from one sample. To overcome this limitation, we propose BitMix, a data augmentation method for spatial image steganalysis. WebData augmentation is a popular technique to inflate the datasets available without collecting new images. For JPEG steganalysis, the augmentations predominantly used by researchers are limited to rotations and flips (D4 augmentations). This is due to the fact that the stego signal is erased by most augmentations used in computer vision.
