We propose a new reversible watermarking algorithm. and the same embedding scheme with OELM-RCP are presented in Figure 15, from which it is observed that, compared with the PSNR achieved by RCP under the same pure hiding rate, Also, from Figures 10, 11, and 14, it is observed that the prediction performance of OELM-RCP is better than those of OELM-MED and OELM-GAP.Figure 14: Comparisons of average absolute prediction errors check over here Our algorithm exploits the redundancy in the image to achieve very high data embedding rates while keeping the resulting distortion low. ©2004 IEEE.
