Watermarking Algorithm Based on Multi-scale Error Diffusion
A new watermarking algorithm is presented based on multi-scale error diffusion,it hides information in the low dot percentage area,which has better data recovery performance than the area of high dot percentage.This technique enhances the performance of watermark extraction,and provides a new choice for the application of digital watermark in printed images.
