Robust Digital Image Watermarking based on Hybrid DWT and GWO Optimization Technique
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 10
Abstract
This paper proposes a novel optimization method for digital images in the Wavelet Transform (DWT) domain. Digital image watermarking has demonstrated its proficiency in ensuring illegal confirmation of data. The visibility factor of the watermark is the huge parameter that helps in enhancing the perceptual transparency and robustness of watermarking system. The trade-off between the transparency and robustness is considered as an optimization problem and is explained by applying GWO Optimization technique. The Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE), and computational time are evaluated for an arrangement of images using the MATLAB R2014b software.
