A Digital Watermarking Method Based on Fast Independent Component Analysis
Wei Wang · Shandong Electronics · 2005
The paper proposes a digital image watermarking method based on FastICA (Fast Independent Component Analysis).In this method, the host image is transformed into discrete wavelet domain. A binary image is embedded to the approaching sub image. When extracting the watermark, a FastICA method is employed. The experiments show that the algorithm has good transparency and robustness.
