The Watermarking Technology Based on Fractal Theory
Bo Zhang · Microprocessors · 2009
This article proposed a method of embedding watermarking into an image by using fractal compression scheme.When embeding watermark,we search the first-matched domain blocks and second-matched domain blocks based on interlacing domain partition,whether swaping the position of the first-matched domain blocks and second-matched domain blocks or not is decided by the watermark bit.Experimental results show that the proposed method degrades the image quality little and has good robustness to noise disturbance,to compressing,to median filtering attacking.
