主 题:mobile video HMD with mobile robust watermarking
摘 要:In head mounted display(HMD),in order to cancel pincushion distortion,the images displayed on the mobile should be prewarped with barrel *** copyright of the mobile video should be verified on both the original view and the pre-warped virtual view.A robust watermarking resistant against barrel distortion for HMDs is proposed in this *** mask is embedded into image in consideration of imperceptibility and robustness of *** order to detect watermark from the pre-warped image with barrel distortion,an estimation method of the barrel distortion is proposed for ***,the same warp is enforced on the embedded watermark mask with the estimated parameters of barrel *** correlation between the warped watermark and the pre-warped image is computed to predicate the existence of *** shown in experimental results,watermark of mobile video can be detected not only from the original views,but also from the pre-warped virtual *** also shows that the proposed scheme is resistant against combined barrel distortion and common post-processing,such as JPEG compression.
