摘要A visible reversible image watermarking scheme embeds visible watermark into digital images for ownership identification and the embedded watermark can be removed to recover the original image. The proposed scheme first partitions the cover image to four similar images with half size in width and height. These 4 images are classified to two sets, fixed set (FS) and watermarked set (WS), and each image is then applied to forward wavelet transform for acquiring 4 low-pass subimages for embedding watermark image. The number of FS and WS determines the stability or visibility of embedded watermarks. The coefficients in FS are stationary and the watermark image is embedded into low-pass coefficients of WS based on low-pass coefficients of FS. Experimental results show that the proposed scheme has good watermark similarity and good extraction result under cropped or noise attacks.
