A Watermark Evaluation Bench for Content Adaptation Modes

摘要

Watermarks embedded in scalable coded media have to be robust to content adaptation (CA) to address network, display and usage requirements. A modularised flexible formal framework as a watermark evaluation bench for content adaptation modes (WEBCAM) is presented. WEBCAM-phase 1 allows evaluation of the effect of various design parameters in wavelet-based watermarking on robustness to CA.
