Abstract: In a method, computer program, and system a dental target, such as a tooth, is located within a digital dental image. A reference object that was placed in the patient's mouth is segmented within a digital dental image to provide a segmented reference. The reference object has a predetermined size dimension. A window is segmented in the dental image at the position of the dental target. The segmented reference defines the relative size and location of the window, prior to the segmenting of the window.

Abstract: The invention relates to a device for the automatic determination of the shade of an object (10), comprising a light source, a light sensor, arranged such as to sample the light reflected or passed through the object (20, 30, 40) in a region of the object, and further comprising means for the determination of the wavelength of said light after reflection or passing through the object, said means providing a spectrometric recording corresponding to the sampling region. The above is characterised in that the means for analysis are provided to analyse a number of such spectrometric samples corresponding to different regions (20, 30, 40) of the object (10) and to identify an average spectrometric value from said set of spectrometric samples.

Abstract: The invention concerns a dental colorimetry measuring apparatus comprising: a white light source, means for projecting the light flux emitted on a tooth to be measured, means for collecting the flux diffused by the tooth, means for spectral selection of the diffused flux, means for measuring spectrally selected light fluxes, means for processing the result of said measurements for classifying the measured tooth relative to a dental shade guide. The apparatus comprises a transceiver set and a measuring head urged into contact with the tooth to be measured, the measuring head being connected to the transceiver set through a fiber optic bundle. The measuring head includes an electric switch triggered by pressing the head on the tooth and controls measurement.

Abstract: A method and systemof image processing on a computer, and a computer program product adapted for image processing, wherein a digital image of an article is improved into a computer, the digital image is colour-corrected, an internal palette is generated from a database of predetermined colour attributes and applied to teh colour-corrected digital image so as to generate a second digital image, and wherein a third digital image corresponding to the second digital image is generated, but replacing the predetermined colour attributes with vivid colour attributes. The present invention is of particular utility in the manufacture of dental prestheses from ceramics materials which substantially match a person's natural tooth colours.

Abstract: Method for measuring the colour of a patient's tooth, e.g. for preparing a dental prosthesis, by which method a measuring probe (1) is placed adjacent the tooth, light being emitting from the probe (1) which after reflection from the surface of the tooth is received by the same probe (1). The measuring probe (1) comprises two light conductor members (2, 3), one for transmitting light and one for receiving light, the first light conductor member (2) being formed of a bundle of light conductors concentrically arranged in relation to the second light conductor member (3). A spectroscopic member (7) communicating with a processor means (8) determines the shade of the tooth in relation to a given colour guide.

Abstract: Color/optical characteristics measuring systems and methods are disclosed. Perimeter receiver fiber optics/elements (7) are spaced apart from a central source fiber optic/element (5) and received light reflected from the surface of the object (20) is measured. Light from the perimeter fiber optics (7) pass to a variety of filters. The system utilizes the perimeter receiver fiber optics (7) to determine information regarding the height and angle of the probe (1) with respect to the object (20) being measured. Under processor control (20), the color measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence, and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe (1) may have a removable or shielded tip for contamination prevention.

Abstract: Le procédé décrit utilise un ordinateur pour faire concorder la couleur d'articles photographiés au moyen d'une caméra vidéo immobile avec un groupe de couleurs de référence. Les photographies sont stockées sur une disquette (34) qui est lue sur un enregistreur (54). L'ordinateur (55) compare le groupe des couleurs de référence avec un groupe absolu de couleurs et produit un facteur de compensation qui est appliqué aux couleurs photographiées, de façon à produire une photographie corrigée. On peut sélectionner des zones de la photographie corrigée pour leur apporter une amélioration par ordinateur et on peut établir par ordinateur une table de correspondance pour faire concorder la couleur d'autres articles avec celle des articles photographiés.
