摘要： What is disclosed is a system and method for estimating color for pixels in an infrared image. In one embodiment, an infrared image is received which has been captured using a N-band infrared imaging system comprising a multi-spectral camera or a hyperspectral camera. The IR image is composed of an array of pixels with N intensity values having been collected for each pixel in the image. Then, for each pixel of interest, a search metric is used to search a database of vector samples to identify a visible-IR set which is closest to the intensity values of the IR band vector collected for the pixel. A visible vector representation is then estimated for the pixel based upon the visible portion corresponding to the closest visible-IR set. Thereafter, color coordinates for this pixel are computed from the visible vector. The method repeats for all pixels of interest in the IR image.

摘要： What is disclosed is a system and method for image-based determination of carbon dioxide (CO2) concentration in exhaled breath. In one embodiment, an image of the exhaled airstream of a subject of interest is received. The image is captured using a mid-wave infrared camera system having an optical filter tuned to the infrared absorption band of CO2. The image is preprocessed to isolate a region of pixels containing the exhaled airstream and intensity values of pixels in the identified region are normalized by a value of a known radiance such as that of the subject's nose or face. The image is analyzed to determine CO2 concentration levels of the exhaled airstream using a calibration curve which relates pixel intensity to CO2 concentrations. The calibration curve is derived using a physics-based parameterized model. The CO2 concentration levels are determined and communicated to a computer workstation. Various embodiments are disclosed.

摘要： What is disclosed is a novel system and method for controlling process color in a color adjustment system in an image marking device. A control parameter, such as a gain matrix, forms a basis of an adaptive closed-loop controller. A sensitivity matrix is used to calculate the gain matrix. This permits complex color adjustments at a customer location. The present system and method is well suited for long production runs because, as the system moves (or drifts) away from nominal, the color control system will learn the changes in the system (e.g., new input-output sensitivity) with print, measure, and prediction processes, operating on the test patches, and effectively adapt to these changes by re-computing the feedback controller gains and revising the current actuator values to follow desired target color values. The present system and method can also be used for adjusting or developing a CMYK recipe in color management LUTs.

摘要： A device, system, and method for reducing the pitch-to-pitch variation of color using pitch-based linearization of halftone screens are presented. A selection of images is printed at different pitches, and each image is measured and tracked with its pitch. Pitch-based TRCs are constructed using patches, which may be scheduled during print run or during machine diagnostic process and halftone dots are constructed and uploaded in the image path for each pitch. The updated dots are then used to produce a linearized halftone image for transfer to a print surface which results in improved color balance.

摘要： What is disclosed is a novel system and method for retrieving a gamut mapping strategy from a seed profile of a seed device. In a manner more fully described herein, the present method provides an embodiment which accounts for the pathological case of a false gamut mapping ray being produced in those instances where the shapes of the gamuts of the host and seed devices are substantially different. In these instances, the rays miss the boundary surface of the host gamut and intersect the boundary of the L*a*b* cube. Another embodiment is provided which accounts for those cases wherein the ray intersects the host gamut at a substantially oblique angle such that mapped color is sufficiently different to generate contours in the output print.
