An Optimized IWT–DCT Watermarking Scheme Based on Multiple Matrix Decomposition and MOWOA2

In this paper, we propose a mixed-domain watermarking algorithm based on integer wavelet transform (IWT), discrete cosine transform (DCT) and multiple matrix decomposition. The combination of IWT–DCT avoids the rounding error of discrete wavelet transform (DWT) in the existing algorithm, so it has b...
