| Abstract: | The scrambling algorithms and scrambling period of Arnold transform, Affined transform and Baker transform in digital watermarking signal pretreatment are designed in this thesis. The scrambling periods of different size images provide basis that different watermarking signals select different scrambling transforms. |
