    Abstract: A method for establishing a relationship between a physical structure of reflectance spectra as defined in a Euclidean color space and a perceptual space of color appearance defined in terms of human perception of colors is performed by obtaining a cube root spectrum of the physical reflectance spectrum in a selected spectral range, reconstructing the cube root of the physical reflectance spectrum by a weighted linear combination of three basis functions, the weights of the linear combination of the basis functions constituting the coordinates in a three-dimensional Euclidean color space with respect to which similarities and differences among reflectance spectra in metric terms and a color characterized in a perceptual space of color appearance can be analyzed, and making an analytic comparison between a physical system in the three-dimensional Euclidean color space and the perceptual system by means of a linear transformation therebetween.

The spectrophotometric scanner comprises a scanner head for collecting spectral reflectance data, a positioning mechanism for positioning the scanner head in relation to a surface, and a computing device for controlling the mechanism and recording and analyzing the spectral reflectance data. The computing device directs the positioning mechanism to position the scanner head on a row of locations in a grid of locations of the surface; directs the scanner head to measure spectral reflectance data for each location in the row of locations; records and analyzes the spectral reflectance data; and produces spectral reflectance images from the spectral reflectance data. A light source in the scanner head comprises a plurality of sequentially controllable LEDs, each producing light in a different wavelength band.

    Abstract: To determine spectra, integrated multiple illuminant measurements from a non-fully illuminant populated color sensor may be converted into a fully populated spectral curve using a reference database. The reference database is partitioned into a plurality of clusters, and an appropriate centroid is determined for each cluster by, for example, vector quantization. Training samples that form the reference database may be assigned to the clusters by comparing the Euclidean distance between the centroids and the sample under consideration, and assigning each sample to the cluster having the centroid with the shortest Euclidean distance. When all training samples have been assigned, the resulting structure is stored as the reference database. When reconstructing the spectra for new measurements from the sensor, the Euclidean distances between actual color samples under measurement and each cluster centroid are measured. The spectra are then reconstructed using only the training samples from the cluster corresponding to the shortest Euclidean distance, resulting in improved speed and accuracy.

    Abstract: The scanner comprises an integrated photosensitive linear sensor (20) comprising N parallel lines of photosites, where N≧4, and preferably N≧6, with each line of photosites being associated with a respective bandpass optical filter. For each scanning step and for each pixel of the analyzed line, it delivers N corresponding quantized partial measurement values, each representative of the spectral reflectance of the document sensed through respective ones of the N filters. Spectral reconstruction means operate using an extrapolation method based on training from reference color samples, having a memory (42) storing a knowledge base formed from known spectral reflectance values of said reference samples, and a neural network (40) receiving as inputs the N quantized partial values and delivering as output at least one reconstituted quantized value representative of the spectral reflectance of the corresponding pixel of the document.

    Abstract: Optical characteristic measuring systems and methods such as for determining the color or other optical characteristics of teeth are disclosed. Perimeter receiver fiber optics are spaced apart from a source fiber optic and receive light from the surface of the object/tooth being measured. Light from the perimeter fiber optics pass to a variety of filters. The system utilizes the perimeter receiver fiber optics to determine information regarding the height and angle of the probe with respect to the object/tooth being measured. Under processor control, the optical characteristics measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence, gloss and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe may have a removable or shielded tip for contamination prevention. A method of producing dental prostheses based on measured data also is disclosed. Measured data also may be stored and/or organized as part of a patient data base.
