Adaptive bistable stochastic resonance based blind watermark extraction in discrete cosine transform domain
Abstract Blind watermark extraction in discrete cosine transform (DCT) domain has a wide application prospect as well as a challenging subject. The imperceptibility of watermark signal makes watermark extraction a weak signal reception issue in essence. For DCT coefficients of host image generally d...
