| Watermarking Similarities Fractal code | |
| This paper describes a digital watermarking scheme based on fractal codification for 8-bit gray scale images; it replaces range blocks by modified blocks according to the watermark bit being embedded. The main contribution of this work is a decrease in the distortion generated by the watermark embedding in the carrier image compared to the reference scheme based on fractal codification; in addition, the scheme achieves a better robustness against JPEG attacks, a decrease at 13.2 dB in distortion and up to 50% improvement in Bit Correct Ratio (BCR). The scheme relies on the selection of interest points, local searching regions and embedding regions to be successful. Finally, this document presents a comparison of the results obtained with the proposed scheme and other schemes inspired by the fractal codification. | |
