Color separation system with angularly positioned light source module for pixelized backlighting.
A color-separation system that angularly positions color LEDs to produce color separation and a lens array to focus this light onto the pixels is proposed. The LED rays from different incident angles are mapped into corresponding sub-pixel positions to efficiently display color image, which can be used to replace the absorbing color filter in the conventional liquid crystal layer. In this paper...
متن کاملPer-separation clustered-dot color halftone watermarks: separation estimation based on spatial frequency content
A framework for clustered-dot color halftone watermarking is considered, wherein watermark patterns are embedded in individual colorant halftones prior to printing and embedded watermarks are detected from scans of the printed images after obtaining estimates of the individual halftone separations. The principal challenge in this methodology arises in the watermark detection phase. Typical thre...
متن کاملSpatial and temporal separation in overdamped systems
Due to their small sizes molecular systems are often overdamped. Conformational changes in these molecules are a consequence of the separation of the energy input between the different displacements and velocities of the different functional sites of the molecule. We show how a simple mechanical device, that splits the forces between the different parts of the system, can achieve spatial (displ...
متن کاملModel Based Color Separation for CMYKcm Printing
Recently, with the advent of printers with more than four colorants, the development of characterization and calibration techniques for these printers has been an important area of research in color printing. In addition to the ”hi-fi” printers having colorants such as green, orange, red, blue and violet to increase the gamut of traditional CMY K (cyan, magenta, yellow, black) printers, CMY Kcm...
متن کاملSpectral-Based Six-Color Separation Minimizing Metamerism
A spectral-based six-color printer model was derived in determining the six color separations for an input spectral image that yields the least metameric reproduction relative to the original. Confined by the ink-trapping limitation, the six-color halftone printer modeling effort is a union of ten four-color halftone printer modeling efforts in addition to a four-ink selector. The four-ink sele...
