- W3018889089 abstract "In this paper, a novel RDH scheme by flipping pattern pairs with opposite center pixel (PPOCPs) in binary images is proposed, aiming at decreasing the distortion while increasing the embedding payload. First, 25 patterns in the 3×3 block are designed which construct the PPOCPs according to the distance level providing a guarantee for reversibility. Then, a balanced score is designed which considers both visual distortion and embedding payload to select the optimal PPOCP, and the secret messages are embedded in the optimal PPOCP. For the receiver, the secret messages can be extracted precisely and the original binary image can be recovered by scanning the optimal PPOCP. PPOCP is a novel RDH model which fully considers the visual distortion caused by flipping pixels. Experimental results demonstrate the feasibility of the proposed RDH method for binary images, and the visual quality is satisfactory under high embedding payload and smallest pure flipping rate." @default.
