Jun 21, 2022 · In this paper, we propose a novel reversible data hiding in encrypted images (RDH-EI) method that achieves the highest hiding capacity in ...
This scheme employs an iterative approach to embed the secret data into the compressed codes of BTC. In each round, the quantization levels are processed by the ...
proposes two RDHEI approaches [32] based on. MSB prediction, i.e., high-capacity reversible data hiding approach with correction of prediction errors (CPE-HCRDH).
A general framework for partial reversible data hiding is proposed in this paper. The original image is adjusted to form a cover image in image transferring ...
Feb 7, 2024 · We propose BDBE as a novel block encoding method, which is the first work to encode the distances of values in a binary block from both ends.
Wang et al. [24] proposed a reversible data hiding technique in LZW code where the value of the LZW code changes or remains unchanged based on the dictionary ...
We now analyze the performance of iterative decoding for asymptotically large random LDPC codes on the BEC. Our method is a special case of a general method ...
