摘要： The present disclosure relates generally to signal encoding for elements within PDF files. One implementation encodes an artwork element under different encoding conditions, and selects a winner version based on resulting signal robustness and/or visibility. Other implementations generate PDF layer masks to help determine overall embedding robustness, including interference from layered elements. Other implementations are provided too.

摘要： An image processing apparatus includes: a first obtaining unit configured to obtain an original image; a second obtaining unit configured to obtain region information indicating first and second regions, the first region read in reading of a print original to have a higher density than the second region, the second region read in the reading to have a lower density than the first region; an embedding unit configured to embed information in the original image by embedding a pattern with a directivity in the first region and embed, in the second region, a pattern in which the number of pixels printed adjacent to printed pixels is smaller than that in the first region; and a control unit configured to perform control of outputting the print original by using a print image in which the patterns of the first and second regions are embedded by the embedding unit.

摘要： Optical code signal components are generated and then transformed into signal bearing art that conveys machine readable data. The components of an optical code are optimized to achieve improved signal robustness, reliability, capacity and/or visual quality. An optimization program can determine spatial density, dot distance, dot size and signal component priority to optimize robustness. An optical code generator transforms tiles of an optical code or image embedded with the optical code into signal-bearing art using stipple, Voronoi, Delaunay or other graphic drawing methods so as to retain prioritized components of the optical code. The optical code is merged into a host image, such as imagery, text and graphics of a package or label, or it may be printed by itself, e.g., on an otherwise blank label or carton. A great number of other features and arrangements are also detailed.

摘要： An image forming apparatus includes an encryption processing unit, a storage unit, a decryption processing unit, a decryption processing unit, and an image output unit. The encryption processing unit encrypts non-compressed image data that is not compressed and indicates a raw image as a target of the forming to generate encrypted image data. The storage unit stores the generated encrypted image data. The decryption processing unit decrypts the stored encrypted image data to restore the non-compressed image data. The image output unit forms the print image on the print medium using the non-compressed image data to output a printed matter. The image forming apparatus regards and processes the encrypted image data as the non-compressed image data to generate encryption confirmation image data indicating an encryption confirmation image, so as to associate and then display the encryption confirmation image with the printed matter using the encryption confirmation image data.

摘要： A computer-implemented process can be operated to create a watermarked copy of a unique original copy of an electronic sales receipt in a first computerized device to a second computerized device. The watermarked copy includes an electronic watermark identifying the copy. The process includes creating the watermarked copy of the electronic sales receipt by copying information from the original copy of the electronic sales receipt to the watermarked copy and providing the electronic watermark within the watermarked copy.

摘要： A data-bearing image (391) is created from a carrier image (371). The carrier image (371) is scaled to produce a scaled image. A clustered-dot halftone screen is applied to the scaled image to produce a halftone image. A resulting number of cells in the halftone image conforms to a cell count (372) that includes a horizontal cell value and a vertical cell value. Payload data is encoded into the halftone image to produce a data-bearing halftone image, including shifting pixel clusters within cells of the halftone image that include pixel clusters.

摘要： A method is provided for inserting a digital watermark in an image by an insertion device. Inserting includes: applying a Fourier transform to the image, delivering a 2D Fourier spectrum; inserting the watermark in the Fourier spectrum delivering a modified Fourier spectrum; and applying an inverse Fourier transform to the modified Fourier spectrum delivering a watermarked image. The watermark includes a set of watermarking coefficients each associated with a distinct determined position of a given quadrant among the quadrants of the Fourier domain, the spectral coordinates u and v of which, measured along the two axes of coordinates of the given quadrant and starting from the continuous component and expressed in percentage of the dimensions U and V of the given quadrant, are such that: u>66%×U and v>66%×V. The set of positions associated with the watermarking coefficients defines a convex pattern in the given quadrant.
