Comparison of Digital Image Watermarking using Hybrid DWT-DCT Algorithm with Fuzzy-Based Algorithm for Improving PSNR

Comparing the Fuzzy-Based method with a Hybrid DWT-DCT method, the purpose of this study is to enhance the Peak Signal-to-Noise Ratio for Digital Image Watermarking. This will be accomplished by employing the hybrid algorithm. For the purpose of conducting a comparative study of digital picture watermarking, a new hybrid DWT-DCT method is used. Group 1 and group 2 are both fuzzy-based algorithms, and each group contains ten samples (n = 10) for the purpose of the analysis. Changing the variables that are entered enables this job to be carried out. The G power test has a value of around 80% (the parameters for the G power setting are α=0.05 and power=0.80). Compared to the fuzzy-based method, which has a PSNR of 97.01 dB, the unique hybrid DWT-DCT algorithm has a higher PSNR of 99.23 dB, and it has a significance value of 0.001 (two-tailed, p<0.05). Comparatively speaking, the power spectrum noise ratio (PSNR) of the new Hybrid DWT-DCT method is higher than the PSNR of the fuzzy-based algorithms.
