摘要:
A method of improving processing of a color natural scene image defined by color density signals processed by multiple processing elements, wherein after an exposure processor incorporates a luminance signal histogram, a modifying TRC curve is derived and applied to the luminance histogram signal. The resultant modified luminance histogram signal is blurred prior to directing it to a contrast processor. The modifying TRC curves determined at each processor are combined and applied to the color density signals only after combination.

A system facilitates printing of microtext. A processing component allows a user to create one or more microtext characters, wherein the characters are output as a data packet. An SRE code store receives and associates one or more SRE codes with the data packet, each SRE code is representative of a bit pattern, wherein the bit pattern is a grid of bits that are filled to create a particular pattern. A font bank receives the one or more SRE codes from the SRE code store and defines such codes via a font. A raster image processor receives the font from the font bank, decodes the font and outputs instructions to print the microtext.

A method of creating a structural document may include determining, by a host computing device in a cloud system, a shape of a structural document, determining, by the host computing device, a plurality of dimensions of the structural document, receiving information associated with one or more content items, and causing a graphical representation of the structural document to be displayed at a user computing device. A shape of the graphical representation may correspond to the determined shape, a plurality of dimensions of the graphical representation may correspond to the determined plurality of dimensions, and the graphical representation may include at least a portion of the received content items. The method may include receiving an indication that a user is finished creating the structural document, generating a print document including an encoded data mark, and providing the print document to one or more print-related devices.

A method and system for creating guilloché base pattern with two-dimensional periodicity in a plurality of replicate patterns is shown wherein the creating can be assessed in real-time for pattern acceptability by a user. A base pattern is set on an imaging device in vector space relative to a set of predetermined pattern nodes. The base pattern is modulated via a user interface by adjusting positions of the pattern known for selectively controlling curve shapes of the pattern. A guilloché mark is illustrated by display on the imaging device of the adjusted base pattern and a compilation of associated replicate patterns for user assessment of the mark.

An image watermarking method includes a color transform on RGB image data to derive CMYK image data that define a constant K image. Variable infrared (IR) mark data defining an IR mark are received and a sparse two-dimensional pattern of black pixels is defined that corresponds to the variable IR data, e.g., using Gold codes or pseudorandom binary sequences. A watermarked black separation K″ is defined by embedding the sparse two-dimensional pattern into the constant K black separation K′ while maintaining local average levels. A watermarked image includes the watermarked black separation K″ in combination with the CMY separations of the constant K image. A decoding process includes using an IR microscope fitted with IR LEDs and an IR pass filter to capture an IR image, which is subjected to exposure correction, thresholding, and dilation operations to extract the two-dimensional pattern for subsequent correlation processing.

As set forth herein, a computer-implemented method facilitates replacing text on cylindrical or curved surfaces in images. For instance, the user is first asked to perform a multi-click selection of a polygon to bound the text. A triangulation scheme is carried out to identify the pixels. Segmentation and erasing algorithms are then applied. The ellipses are estimated accurately through constrained least squares fitting. A 3D framework for rendering the text, including the central projection pinhole camera model and specification of the cylindrical object, is generated. These parameters are jointly estimated from the fitted ellipses as well as the two vertical edges of the cylinder. The personalized text is wrapped around the cylinder and subsequently rendered.

A portable electronic device includes an image capture module that captures a digital image of a symbology that is affixed to a regulated product. The device decodes the symbology to identify an end user functional element which has a public component and a law enforcement component. If the device has received a law enforcement official verification, then the device may use the law enforcement component of the functional element to take a first action. If the device has not received the law enforcement official verification, then the processor device may use the public component of the functional element to take a second action.

A system/method of color match assessment for electronic documents includes receiving digital data defining a composite electronic document including a raster image object having an edge and a color graphics object bordering the edge of the raster image object. The pixel color values defining the edge of the raster image object are processed to estimate a local color variance of the pixel color values. The local color variance is used to determine if the edge can be color matched to the bordering color graphics object. If the edge can be color matched, a match color for the edge is derived. The match color is associated with the digital data defining the electronic document so that a downstream object color match system can use the match color as needed.
