Abstract
A newly discovered color watermarking approach is instigating in this paper which is rely upon whale optimization algorithm. YIQ color space is more applicable for the human visual system in the real time applications so the color cover image is changed from RGB color transformation to YIQ color transformation. Moreover, perform three-level discrete wavelet transform - singular value decomposition to luminance component (Y). In the image watermark embedding approach, perform DWT to a watermark gray image after executing the scrambling encryption process using generalized Arnold transform (GAT). The proposed algorithm uses whale optimization algorithm to pick the precise multi-scaling factors. The results from simulation predicated that the proposed watermarking pattern is improved and satisfied the properties of watermarking such as imperceptibility and robustness.
