Abstract

En 中文
In this paper, an image refining technique is proposed. The digital watermarking and RS coding techniques are adopted to provide the image refining. The RS codewords' parities of original image are used as a watermark to be embedded in the original image. The watermark can provide the error correction and detection capability for the original image (refining function). Meanwhile, we take the advantage of the parity bits of rearranged DCT coefficients in the lower frequency subbands of quantized DCT block to provide the robustness and imperceptibility requirement for watermarking technique. The proposed method can directly extract the embedded watermark from the watermarked image without using original image so as to implement it to the real time system is feasible. The experimental results show that the error correction and detection capability, imperceptibility, and robustness of the watermarking technique can be guaranteed.
