Abstract :
The chaotic characteristics of cellular automata are analyzed simply and the fractal box dimensions of cellular automata are computed. Based on the box dimensions, one can choose chaotic cellular automata to scramble digital image as a pretreatment for the watermarking process. Experimental results show that watermark images embedded by this technique are robust against various attacks, such as noising, cropping, JPEG compression. The chaotic characteristics of cellular automata are rather well in the application field of digital images.
