摘要： What is disclosed is a system and method for compensating for differences between two spectrophotometers for accurate color control in a color management system. In one example embodiment, at least one print is generated on the digital color printing system incorporating an inline spectral reflectance measurement sensor. A spectral reflectance of the print is measured using an inline spectral reflectance measurement sensor. Spectral reflectance of the print is measured using a selected offline spectral reflectance measurement sensor. From the measurements, a sensor correction model is determined which transforms spectral measurements obtained from the inline sensor into spectra approximating what the offline sensor would measure. The sensor correction model is used to perform color management on the digital color printing system such that print output of the digital color printing system is accurate when measured on the offline sensor.

摘要： What is disclosed is a feedback control based system and method for selecting spot color recipes for improved spot color rendition while simultaneously minimizing a function of image quality attributes formed with states defined as vectors such as L*, a*, b*, mottle, graininess, etc. Color is measured with an in-line spectrophotometer or with a full/partial width array. If the sensor is not available, then a model of the print device is used to optimize the function of image quality attributes. In one example embodiment, a spot color of interest is selected along with a set of image quality attributes to be improved for the spot colors of interest. Set points for process actuators and color recipes of the color marking device are adjusted such that a function of the image quality attributes is minimized when the spot color is rendered on the device. Various workflows are disclosed.

摘要： What is disclosed is a method for vehicle occupancy detection using a single band infrared imaging system. First, an infrared image of a vehicle intended to be processed for human occupancy detection is captured using a single band infrared camera set to a predefined wavelength band. A candidate sub-image is identified within the captured image. A cumulative histogram is formed using the reflectance values of each pixel in the candidate region. A threshold reflectance value is then determined from the cumulative histogram using a pre-defined cumulative occurrence fraction value which corresponds to a value equivalent to an average sized human face. Embodiments for setting the threshold reflectance value are disclosed. Thereafter, human occupants can be distinguished in the image from the vehicle's interior by comparing pixel reflectances in the sub-image against the threshold reflectance value.

摘要： What is disclosed is a system and method for post-processing a multi-spectral image which has already been processed for pixel classification. A binary image is received which contains pixels that have been classified using a pixel classification method. Each pixel in the image has an associated intensity value and has a pixel value of 1 or 0 depending on whether the pixel has been classified as a material of interest or not. A block of size m×n is defined. Pixel values in a block are changed according to a threshold-based filtering criteria such that pixels in the same block all have the same binary value. The block is then shifted by k pixels and pixel processing repeats until all pixels have been processed. Once all blocks have been processed, contiguous pixels having the same binary value are grouped to form objects. In such a manner, pixel classification errors are reduced.

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.
