The optimal scaling factor based on Secant Method for image watermarking using the hybrid DTCWT-DCT domain
This paper proposes an implementation of the secant optimization method on the watermark embedding in DTCWT domain. An objective function combining PSNR and NC (The Normalized Correlation) values calculated for a set of common attacks is used in the optimization process. The aim is to enhance the t...
