WebJan 21, 2024 · For J-UNIWARD at 0.1 bpnzac at JPEG quality 75, increasing the number of filters from 12 to 24 leaded to an increase of PE of about 4%. Decreasing the number of filters under 12 leaded to decrease in detection accuracy and increasing the number of filters beyond 24 did not seem to a significant change in detection performance. 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.
