Kits, diagnostic systems and methods are provided, which measure the distribution of colors of skin features by comparison to calibrated colors which are co-imaged with the skin feature. The colors on the calibration template (calibrator) are selected to represent the expected range of feature colors under various illumination and capturing conditions. The calibrator may also comprise features with different forms and size for calibrating geometric parameters of the skin features in the captured images. Measurements may be enhanced by monitoring over time changes in the distribution of colors, by measuring two and three dimensional geometrical parameters of the skin feature and by associating the data with medical diagnostic parameters. Thus, simple means for skin diagnosis and monitoring are provided which simplify and improve current dermatologic diagnostic procedures.

A device and method for applying a material to a hard surface. The device has a sensor and one or more applicator nozzles. The device further includes a reservoir for containing a material to be deposited, and a CPU. The method includes providing information from the sensor about the surface to the CPU, which uses the information to identify where the material is to be deposited and/or how much to deposit.

The present disclosure relates to a process for printing comprising the steps of selecting eight or fewer process colors from a known process ink color set, providing a color channel for the selected process colors from the known process ink color set, providing two or more spot color channels, wherein one or more of spot colors correspond to a non-selected process color of the process ink color set, applying a first ink limit and a first linearization to the one or more spot color channels to produce a color set including the non-selected process color of the known process ink color set, applying a second ink limit and a second linearization to the one or more spot color channels to produce a color set including the spot color, and optionally printing an image.

An information processing apparatus includes a processor configured to: receive an image; and in response to inputting a magenta component resulting from CMYK conversion of the received image, output the image having undergone color conversion performed by using a profile in which at least one of the magenta component and a pink component that leads to fluorescent color forming is output, in which in an area having an input magenta amount lower than a predetermined threshold, the magenta component is not output and only the pink component is output, the input magenta amount serving as an amount of the magenta component resulting from the CMYK conversion, and in which in an area having the input magenta amount higher than or equal to the threshold, the magenta component and the pink component are output.

The present disclosure relates generally to data hiding for retail product packaging and other printed objects such as substrates. One embodiment embeds an information signal in a spot color for printing on various substrates. The spot color is screened, and overprinted with process color tint. The tint is modulated prior to overprinting with optimized signal tweaks. The optimization can include consideration of a detector spectral dependency (e.g., red and/or green illumination). Many other embodiments and combinations are described in the subject patent document.

The present document provides image processing methods and apparatus. One claim recites: obtaining a signal to be encoded in color image data, the signal comprising a plural-bit payload; predicting a resulting color of overprinting several inks on a substrate, the overprinting representing the color image data encoded with the signal; using the resulting color for both i) visibility evaluation of the overprinting, and ii) signal robustness evaluation of the overprinting as seen by an imaging device. Other claims and combinations are provided.

An image-forming device includes a Central Processing Unit (CPU) and a storage device, wherein the storage device stores a color-conversion program, and the CPU functions as a centroid acquisition unit, a color-conversion-information generation unit, and an output-image generation unit. The centroid acquisition unit acquires a centroid of a cluster of approximate colors in an input image. The color-conversion-information generation unit generates color-conversion information for converting the input image to an output image. The output-image generation unit converts color in the input image, and generates the output image. The color-conversion information is information for moving a color in the input image according to movement of the centroid when moving the centroid to a representative color in a specific range.

An image processing apparatus generates image data used in printing an image on a sheet being attachable to skin. The image processing apparatus includes: an image acquirer that acquires a skin image picked up from the skin; an image analyzer that extracts, from the skin image, a discolored region differing in color from surrounding skin by at least a predetermined level, and surrounding color being color of the skin surrounding the discolored region; a grouping processor that groups a plurality of the discolored regions, and determines an inclusive region for each region group which is a cluster of the grouped plurality of discolored regions or one discolored region not having been grouped, to include the one or a plurality of the region groups; and a printing controller that generates image data having a content of printing a pigment material that causes color of the inclusive region to approximate the surrounding color, on a region corresponding to the inclusive region in the sheet.
