An extended watermarking scheme to integer sequences for broadcast monitoring without using reference images

摘要

This paper proposes an extended watermarking scheme to integer sequence that extracts embedded information without reference images for an automatic broadcast monitoring system. In this scheme, to reduce the amount of extract calculation, watermark sequences are composed of integer numbers and the distribution of sequence components are not restricted. Also, this scheme realizes the watermarked images with desired quality in terms of PSNR. By simulation, it is confirmed the above.
