| Summary: | Digital watermarking technique based on intermediate significant
bit (ISB) has been discussed by this study. This technique can
survive against different types of attacks and at the same time
keep the quality of the image. In this study, two improvement
stages were applied, repeating the embedding and watermark
embedding based on the average of pixels values. The results
showed that the value of the Normalized Cross Correlation (NCC)
was increased by increasing the embedding number of all the
attacks. The results of the NCC for all the attacks became very
close to 1 after nine repetitions. The results indicate that the
method, based on the average of pixels values, is better for all the
attacks as compared to based on repetition, except for rotation and
scaling which improved extensively using the same method. |
