英文摘要 | We propose a reversible data hiding algorithm for mosaic images captured by a single charge-coupled device/complementary metaloxide-semiconductor (CCD/CMOS) sensor with the Bayer color filter array (CFA). Specifically, the algorithm uses prediction errors in the color difference domain to embed hidden data. Since such errors tend to follow a Laplacian distribution, the algorithm’s embedding capacity is high and it generates good quality marked images. The results of experiments on some typical CFA mosaic images demonstrate the efficacy of the proposed approach. |
