A new algorithm on wavelet based robust invisible digital image watermarking for multimedia security

This paper presents a new algorithm on wavelet based robust and invisible digital image watermarking for multimedia security. The proposed algorithm has been designed, implemented and verified using MATLAB R2014a simulation for both embedding and extraction of the watermark and the results of which shows significant improvement in performance metrics like PSNR, SSIM, Mean Correlation, MSE than the other existing algorithms in the current literature. The cover image considered here in our algorithm is of the size (256×256) and the binary watermark image size is taken as (16×16).
