In a print production system, the ability to match a printed document with its original electronic form enables services that improve robustness of the production process, such as...
Abstract-- We present a perceptual model for hiding a spreadspectrum watermark of variable amplitude and density in an image. The model takes into account the sensitivity and maski...
In the field of silver-halide photography, color separation was explored about a century ago, using filter mosaics, dichroic mirrors, three-shot filtration, and other techniques, ...
In this paper we describe a robust approach to segment text from color images. The proposed approach mainly includes four steps. Firstly, a preprocessing step is utilized to enhan...
