A Robust Digital Watermarking Technique using DWT-DCT and Stat ics blocks

This paper introduces a method based on Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT), and the characteristics of the human visual system (HVS). In this method the watermark data is embedded into imperceptibles blocks[1], we used the entropy value to select the suitable blocks. Experimental results show that the visual quality of the watermarked image and the extracted watermark is good in spite of attacks.
