A New Watermarking Pre-processing Algorithm Based On Coding

XU Jin-dong,LIU Da-long(College of Physical Engineering,Qufu Normal University,273165,Qufu,Shandong,,PRC)  
Capacity is one of the most basic requirements for invisible image watermarks.To improve the capacity of watermarks,a new watermarking pre-processing method based on coding is proposed.Firstly,the watermark information is pre-processed by compression coding and error control coding(ECC).And then,the coded watermark sequence is embedded in the discrete cosine transform(DCT) coefficients of carrier image.Theoretical analysis and simulation results show that the watermarks generated with the proposed method are invisible and robust against noise and commonly used image processing techniques,and have higher capacity.
