Abstract :
An adaptive watermarking algorithm in wavelet domain is proposed. The whole process was based on integer wavelet transform, code the significant coefficients which have un-scanned in intermediate frequency sub-band, adaptively quantize wavelet coefficients. The watermark is embedded the perceptually important coefficients. Experimental results show that the algorithm proposed has the following characters: adaptability, implemented fast, invisible and robust against attack such as JPEG compression, filter, noise addition and cropping.
