Embedding robust watermarks by chaotic mixing
G. Voyatzis, Ioannis Pitas · 2002
This paper presents a watermarking algorithm for copyright protection of digital images. A copyright label represented by a binary image is embedded in grayscale or color digital image. A mixing dynamical system controls embedding, detection and reconstruction of the copyright label. Detection of the watermark is succeeded either by direct reconstruction of the watermark as a binary image or by using statistical hypothesis testing.
