A Novel JADE Based Robust Digital Watermarking Algorithm

摘要：

Digital watermarking has become increasingly significant in copyright protection and robustness is a key problem of digital watermarking. This article proposes a robust watermark method based on JADE (Joint Approximate Diagonalization of Eigenmatrixe) 1. This algorithm uses iterative blending to embed watermark and regards watermarked image as one observed signal, watermark image as the other observed signal. In the detect Section, watermark is detected by JADE, which neednt to know the exact location of embedded watermark. Simulation results and theoretical analysis show that this algorithm has stronger robustness and it can better withstands general attacks.
