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 applies the image to 1-D wavelet transform to acquire four similar subimages. The watermark, defined as a binary image, is then embedded into two selected subimages. The embedded strategy enlarges the contrast by raising grey level of darker pixels and reducing grey level of lighter pixels. Experimental results show that the proposed scheme raising the watermark contrast both on darker or lighter pixels. Thus reveals the significant property of our proposed method. Moreover, the computation load is low both in embedding or extracting watermark. |
