Study the Effect of Using a Fuzzy System in a Blind Digital Image Watermarking

This paper studies the effect of using fuzzy system in a blind digital image watermarking scheme which uses a statistical based algorithm for embedding a binary pseudo random sequence into a grayscale host image. It will be shown that the varying watermark power in different regions of host image, increases the imperceptibility of watermark. Experimental results show that the proposed method is robust under different attacks such as compression, cropping, adding noise, scaling etc...
