Adaptive reversible data hiding in frequency domain via integer-to-integer transform

摘要

This paper proposes an adaptive reversible data hiding algorithm for images, which embeds significant information in frequency domain based on integer-to-integer transform. The embedding method is realized by modifying state-of-the-art one according to integer-to-integer transformed coefficients. It overcomes a problem where the conventional method often generates particular artifacts. The simulation results show that our proposed algorithm outperforms the conventional one about the visual quality of embedded images, objectively and perceptually, while keeping embedding capacity.
