摘要： A transform domain watermarking technique which is based on a new encoding scheme referred to as scaled bin encoding which encodes a message in a set of transform coefficients by modifying their values in a way that preserves high image quality (i.e., low distortion levels) and adapts to expected noise level. Recapturing of the watermark image is performed via a decoding method using a maximum likelihood procedure (i.e., maximum likelihood decoding), based on the statistics of the transform coefficients and a worst case statistical model of the noise introduced to these coefficients by image processing operations or attack noise.

摘要： A variational model for spatially dependent gamut mapping is described that includes inputting a gamut constraint, choosing a one dimensional gamut projection scheme, including selecting a transform color coordinate system, computing transform equations, and verifying gamut conditions. The model also includes inputting an original image to be rendered, where the original image is in a given color coordinate system, transforming the gamut constraint, the image, and the transform equations to the transform color coordinate system, whereby a three dimensional function is transformed into a one dimensional quadratic functional, finding a minimum solution to the functional, and transforming a projected image in the transform color coordinate system into a color coordinate system of a rendering device.

摘要： A color defined by a chroma point and by a luma value is adjusted by defining a reference chroma point and shifting the chroma point towards the reference point if the chroma point is within a predefined tilted rectangle in the chroma coordinate plane that encloses the reference point; or if the chroma point is within both of two predefined polygons, in the chroma coordinate plane, that enclose the reference point; or if the luma value is within a predefined luma range. Preferably, the two polygons are a rectangle and a rhombus. The chroma point is shifted using a continuous shift function that vanishes on the rectangle and on the rhombus.

摘要： The present invention relates to novel polymeric compositions that exhibit Reverse Thermal Gelation (RTG) properties for use as Support Materials (SM) in the manufacture of three-dimentional objects. These polymers are Temperature Sensitive Poolymers that respond with a significant change of properties to a small change in temperature. Temperature Sensitive Polymers exhibit cloud point (CP) or lower critical solution temperature (LCST) in aqueous solutions. Water-soluble Temperature Sencitive Polymers are chosen to give low viscosity liquid at low temperature when dissolved in water and by that to permit easy dispensing at low temperature. Rising the temperature above their gelation temperature (Tgel) will result in solidification of the composition. At its gel position the material has favorable characteristics as a support and building material. The gel layers have the appropriate toughness and dimensional stability to support the model layers during the building process. After the building process is completed the gel can be cooled down to a temperature below its Tgel so the gel can liquefy and be removed easily by rinsing with a water.

摘要： Payment indicia generating schemes are described that enable users to customize the appearance of the payment indicium and to accommodate a wide variety of validation processing environments, while providing a substantial defense against fraudulent photocopy attack. In some embodiments, a corroborative digital token is generated from payment information, and a base image is modulated with a graphical encoding of the corroborative digital token to produce a payment indicium. In some embodiments, a payment indicium containing embedded payment information is rendered on a printing surface with a printing characteristic that degrades with photographic reproductions such that the embedded payment information is extractable from an original rendering of the payment indicium but is un-extractable from a photographic reproduction of an original rendering of the payment indicium. In some embodiments, payment information is encoded into a corroborative digital token based at least in part upon one or more variable encoding parameters, and a payment indicium containing the encoded payment information is rendered.

摘要： A method and apparatus for color image processing using gamut mapping reduces halo artifacts by correcting terms in a gamut mapping algorithm. The color image may be represented by f, the in gamut image by g, the target gamut by C, and the gamut constraint by c. The method for reducing halo artifacts includes two correction steps. First a color distance term L2 in the gamut mapping algorithm is corrected. Second, a distance measure of an image gradient in the gamut mapping algorithm is corrected. The first correcting step comprises computing a function u=projectC(ƒ). The second correcting step comprises computing a scaled down function for f. Next, a function g(x,y) is determined that minimizes a functional comprising the color distance term and the image gradient term. The solution may be determined by iteration using a gradient descent operation by first initializing g0=projectC(ƒ), and then performing one or more iteration steps to compute g(x,y).
