The design of an integrated image coding and watermark system with the wavelet transform is examined and a non-invertible progressive watermark scheme is incorporated in MTWC for copyright protection.Abstract:
The design of an integrated image coding and watermark system with the wavelet transform is examined in this work. First, the multi-threshold wavelet codec (MTWC) is used to achieve the image compression purpose. Unlike other embedded wavelet coders which use a single initial threshold in their successive approximate quantization (SAQ), MTWC adopts different initial thresholds in different subbands. A superior rate-distortion tradeoff is achieved by MTWC with a low computational complexity. Then, a non-invertible progressive watermark scheme is incorporated in MTWC for copyright protection. This watermark scheme uses the user input data to produce a Gaussian distribution pseudorandom watermark in the wavelet domain. The performance of the proposed watermark technology is supported by experimental results.read more

Robust watermark method and apparatus for digital signals
TL;DR: In this paper, the authors proposed a method to generate an endless stream of pseudo-random bits from previous bits of the watermark sequence, which are then appended to the stream of pseudorerandom bits and additionally replaced by a number of bits of state.

TL;DR: 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.
