Secure spread spectrum watermarking for multimedia
TLDR
It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.

Secure spread spectrum watermarking for images, audio and video
TLDR
The watermark can be constructed to make counterfeiting almost impossible, and the same digital watermarking algorithm can be applied to all three media under consideration with only minor modifications, making it especially appropriate for multimedia products.

MPEG-4 intellectual property management & protection (IPMP) overview & applications
TLDR
This work describes a framework for MPEG-4 Intellectual Property Management and Protection that provides applications designers with the control necessary to manage these requirements.
Robustness and Security of Digital Watermarks
TLDR
This paper is a brief technical survey of the multimedia watermarking landscape and offers possibly acceptable fidelity and robustness against certain types of processing, but are not sufficiently robust against geometric transforms such as scaling and cropping of images.

TLDR
The compensation method introduced here can discover good matches in regions where patterns overlap occluded regions, and would otherwise be missed, and can be used in conjunction with other criteria, including the normalized correlation coefficient.

Adaptive update algorithms for fixed dictionary lossless data compressors
TLDR
It is argued that by using a "clever" update algorithm, coupled with a compact data structure, a compressor can achieve a more compact data representation than that produced by a non-adaptive or weakly adaptive one.

High-fidelity audio compression: fractional-band wavelets
TLDR
Real-time algorithms for the compression of high-fidelity audio are under study and a subband coding system that performs this is presented that combines a wavelet-based signal transformation block with adaptive quantization and lossless compression blocks.
