An image watermarking technique based on the concept of JPEG2000 algorithm is proposed. Biorthogonal wavelet 9/7 transform is used to provide a set of coefficients suitable for watermark embedding. The statistical properties of different subbands are analyzed in order to choose the number of decomposition levels and position of subbands, which will assure the best compromise between the watermark...
Analysis of quantization effects on watermarked coefficients and watermark is considered. A criterion for selection of coefficients suitable for watermarking in the presence of quantization is derived. The effects of quantization are further analyzed in terms of the probability of detectable watermark and the probability of zero-quantized watermarked coefficients. This analysis is used to define an...
