| Abstract: | Thodi algorithm is improved,and prediction error threshold value and the threshold parameter value defined by simulation experiments.The method has been proved that it can be employed to hide a large amount of information in image,where the original host image from the embedded image could still be retrieved after the hidden data is extracted,and PSNR has been enhanced. |
| Keywords: | Linear-prediction Prediction error threshold value Threshold parameter value Lossless information hiding |
