Filter bank frame expansions with erasures
Abstract--We study frames for robust transmission over the Internet. In our previous work, we used quantized finite-dimensional frames to achieve resilience to packet losses; here,...

Spread spectrum-based watermarking for Tardos code-based fingerprinting for H.264/AVC video
In this paper, we present a novel approach for active fingerprinting of state of the art video codec H.264/AVC. Tardos probabilistic fingerprinting code is embedded in H.264/AVC v...

Fast identification of JPEG 2000 images for digital cinema profiles
A method for identifying JPEG 2000 images with different coding parameters, such as DWT-filters, code-block sizes, quantization step sizes, and resolution levels, is presented. ...
