Matthew L Miller, Ingemar J Cox: Applying informed coding, informed embedding and perceptual shaping to design a robust, high-capacity watermark. NEC Laboratories America, Scully Scott Murphy & Presser, February 7, 2006: US06996249 (67 worldwide citation)

A watermark message embedded in a cover work can be made robust to various types of post-embedding operations, while simultaneously minimizing perceptual impact on the cover work. This is accomplished by the informed coding of the watermark message to be embedded. This is also accomplished by the in ...

Narayan Prasad, Xiaodong Wang, Mohammad Madihian: Spherical lattice codes for lattice and lattice-reduction-aided decoders. NEC Laboratories America, Bao Tran, Joseph Kolodka, January 3, 2012: US08091006 (64 worldwide citation)

Methods and apparatus for designing spherical lattice codebooks for use in data transmission systems are provided. A spherical lattice codebook is constructed by determining the channel statistics of one or more channels, which can be accomplished by observing a sufficiently large set of channel rea ...

Matthew L Miller: Watermarking with cone-forest detection regions. NEC Laboratories America, February 15, 2005: US06856693 (62 worldwide citation)

In a watermarking system, an embedder embeds one of several alternative watermark patterns that represent the source message using side information to improve robustness. A detector uses normalized correlation to test all of the patterns, indicating that the source message is present if any one of t ...

Ingemar J Cox, Matthew L Miller: Robust digital watermarking. NEC Laboratories America, May 18, 2004: US06738493 (53 worldwide citation)

A watermarking procedure that is applicable to images, audio, video and multimedia data to be watermarked divides the data to be watermarked into a set of n×n blocks, such as the 8×8 blocks of MPEG. The same watermark signal can be distributed throughout the set of blocks in a large variety of ways. ...
