A visual sensitivity model based stereo image watermarking scheme

Abstract

We present a visual sensitivity model based method for watermarking high definition (HD) stereo images in DCT domain. Our proposal is devoted to make the stereo image watermarking scheme as robust and invisible as possible. Visual sensitivity refers to the ability of human observers to detect distortion in visual field. In order to achieve the best tradeoff point of robustness and transparency of the watermarked images, the watermarking scheme is based on the visual sensitivity model to determine the perceptual adjustment on watermark insertion. The performance of the proposed method has been tested under various attacks producing very promising robustness results while retaining the watermark transparency.
