Abstract: An object is to quantify the texture such as irregularity and gloss of a metal surface. Centers of Lab chromaticity distributions are identified (S145), and one of the Lab chromaticity distribution is entirely shifted (mapped) by deviations ΔA, ΔB and ΔL of a central coordinate, such that one of central coordinates of two distributions U1(L,a,b) and U2(L,a,b) matches with the other central coordinate (S146). A texture spread index that indicates a difference in spatial spread is then computed (S147). This configuration computes the spatial spread of the Lab chromaticity distribution in a three-dimensional space, and quantifies the irregularity of an inspection plane by diffraction phenomenon of illumination light. The difference in spread other than the color is applicable to evaluation of the irregularity of the metal surface or the like.

Abstract: An unevenness inspection apparatus includes circuitry that is configured to obtain a pickup image of a test object and modify a chroma value of a pixel in the pickup image to correct a gain of the pickup image associated with the pixel for generating a color unevenness inspection image. The circuitry is configured to generate a luminance unevenness inspection image based on the pickup image and calculate an evaluation parameter using both of the color unevenness inspection image and the luminance unevenness inspection image. The circuitry is configured to perform unevenness inspection using the calculated evaluation parameter, which is calculated based on unevenness visibility for both color and luminance.

Abstract: A shade selection program is disclosed that predicts the shade choice with the smallest CIEDE2000 color difference for dental composite resin restorations when given a backing and target shade. By utilizing generated regression models, a database of spectral reflectance information, and principles of Kubelka-Munk layering, a highly accurate shade selection program was designed. Additionally, a blending model for quantification of color adjustment potential was developed. Systems and methods for correlating RGB data from the VITA Linearguide 3D Master and VITA Bleached Guide 3D Master shade guides with their spectroradiometric correlates through a regression model while indicating a methodology for validation of accuracy of digital imaging systems are disclosed.

Abstract: Examples of an imaging sensor include a two-dimensional staring sensor with spectral filter strips for multispectral overhead imaging. The sensor may also include a panchromatic sensor with block or strip filters. The sensor may be used to collect multispectral color image data at a sampling resolution from overhead imaging platforms such as airplanes or satellites. The sensor can be used to provide video images. If a panchromatic sensor is included, the sensor may be used to collect panchromatic image data. Examples of methods for processing the image date include using the panchromatic image data to perform multi-frame enhancement or panchromatic sharpening on spectral images to improve their quality and resolution.

Abstract: A method is provided for the quantitative determination of surface properties, wherein a spatially resolved image of a surface to be analyzed, which contains a large number of measured values, is recorded. In a first method step, the measured values are analyzed in order to determine those surface areas which have a specific physical property. A result value of this physical property is then determined, wherein this result value is characteristic of the values of the physical property of all those surface areas of the image determined by analyzing the image. In addition to the result value, a further value (B) characteristic of the surface is determined and this characteristic value is displayed together with the result value (I).
