Digital Watermarking Algorithm Based on Principal Component Analysis
Xinde Sun · Journal of Taiyuan University of Technology · 2007
Digital watermarking algorithms of multiband images are very important,but most of the algorithms are based on the single frequency band component.In this paper,an algorithm based on principal component is proposed.The steps presented algorithm includes: principal component analysis,DCT transform,Arnold transform,embed watermarks in the principal component.The experimental results show that the algorithm has higher robustness and security.
