REVERSIBLE INFORMATION HIDING FOR BINARY IMAGES BASED ON SELECTING COMPRESSIVE PIXELS ON NOISY BLOCKS

摘要

This paper proposes a reversible information hiding method for binary images. A half of pixels in noisy blocks on cover images is candidate for embeddable pixels. Among the candidate pixels, we select compressive pixels by bit patterns of its neighborhood to compress the pixels effectively. Thus, embeddable pixels in the proposed method are compressive pixels in noisy blocks. We provide experimental results using several binary images binarized by the different methods.
