Cover image에 데이터를 임베딩 하여 stego-image를 생성하고, stego-image로부터 cover image를 손실 없이 복원하며임베딩 된 데이터를 손실 없이 복원할 수 있는 가역 데이터 은닉기법의 성능을 개선하는 효율적인 기법을 제안하였다. 제안된 기법에서의 임베딩 된 데이터 크기는 이전의 기법에 비하여 더 크고, stego-image의 PSNR값은 48dB보다 더 크게되는 것이 보장된다. 실험을 통하여 제안된 기법의 성능을 확인하였다.
Abstract
An efficient reversible data hiding algorithm was proposed in this paper. The original image can be recovered from the stego-image without distortion during the embedded data are extracted from the stego-image. The embedding data are greater than that of the previous algorithm and the PSNR value of the stego-image is guaranteed to be greater than 48dB. The performance of the proposed algorithm was proved by experimental results.
