Abstract

Because of the blocking artifacts resulted from 8×8 Discrete Cosine Transform (DCT), most watermarking technologies have been proposed using DCT whose image quality was not very good. In 1990, Gonzales et al. described a technique which predicts a few low frequency AC coefficients. The AC predictor uses the dequantized DC values of a 3×3 neighborhood of 8×8 blocks to predict the AC values in the center block. Wang proposed a data hiding scheme using the AC prediction technology in 2005. But it is unable to be suitable for the image of all types to predict AC coefficients accurately. We propose a new watermarking system by using the technologies of 4×4 integer DCT transform and adaptive AC estimation. We use 4×4 INTDCT transform to reduce blocking artifacts caused from 8×8 DCT transform and improve Imperceptibility and watermark capacity greatly. Moreover, we utilize AC prediction value as error-checking code to enhance robustness of watermark.
