摘要： This document relates generally to digital watermarking. One claim recites a method including: obtaining data representing visual media; determining a model through iteratively embedding a digital watermark signal in the data; and embedding the digital watermark signal in the data according to the model. The model maximizes robustness of the digital watermark signal while minimizing perceptibility of the digital watermark signal when the signal is embedded in the data. A new embedding form or embedding mask is created after each embedding iteration. Of course, other combinations are described and claimed as well.

摘要： A test pattern printed by a printer is assessed—without colorimetric equipment—to provide data used in recalibrating the printer. The assessment may be made by an unskilled operator, and can include discerning whether a particular pattern is visible in the printed test pattern, or whether a feature in the test pattern is relatively wider or narrower. From such assessment, needed changes to the printer's calibration data are inferred and implemented. A variety of other printer calibration techniques are disclosed. The technology is illustrated in the context of dye sublimation printers, and is particularly useful in optimizing printing of digitally-watermarked graphics.

摘要： A digital watermarking system uses a model of a rendering device to take into account the impact of the rendering device on visual or auditory quality of the watermarked signal. For visual content, a reference image and watermarked image are passed through the model and then supplied to a visual quality metric that assesses the visibility of the watermark. The digital watermark embedding is adjusted iteratively with each pass through this process to produce a watermarked signal that has the desired visual quality.
