Abstract EN
Reversible data hiding (RDH) is a method that allows a cover image to be completely recovered from its corresponding stego image without distortion after the embedded secret messages have been extracted.
Prediction-error expansion (PEE), as a classic RDH scheme, has been studied extensively due to its high quality of stego images.
Based on prediction errors, threshold values, and the relative distances between each bin and zero bin, we present a bidirectional shift and double-way prediction strategy to solve the multiple embedding problem.
Compared with the original algorithm, this scheme only takes a little more time and reduces the PSNR slightly, but it improves the embedding capacity significantly and allows for reversible data hiding.
When both threshold values of TH and TH∗ are equal to 2, the average ER value of 108 test images is 1.2 bpp which is ideal for medium data payload.
At the same time, the PSNR is above 30 dB, making embedded information visually imperceptible.
These data, together with other experimental results, show that the method proposed in this paper has obvious advantages in image quality and embedding capacity.
