Abstract: A process for preparing discrimination criteria for color identification comprises reading values representing a plurality of color components delivered from a color sensor for each of a plurality of given reference colors, calculating relative values of the color components, calculating relative values of the color components, calculating the deviation of the relative value of each color component from a specified value, extracting pairs of deviations each having a discrimination distance of at least specified times relative to any other reference color, determining a discrimination criterion between the extracted pair of deviation, and repeating the extracting and determining steps by calculating deviations of higher order with use of the deviations until discrimination criteria are determined for all the given reference colors.

Abstract: Apparatus for color grading of products such as fruits, vegetables, et cetera, employing a light source for illuminating the product and means for detecting and comparing the reflectance to measure certain product properties. For calibration, a target of known color is moved in front of the light source and the resulting signal is compared with a reference signal to generate a modifying signal. For automatic calibration of the apparatus this modifying signal is stored and thereafter used to adjust all subsequent readout signals.

Abstract: General purpose designation method and apparatus for designating the class to which an unknown event or observation belongs among a plurality of possible classes. In the most generalized sense, designation is accomplished by establishing a multidimensional coordinate system in which each axis represents a different selected property or characteristic that is relevant to the particular designation operation being carried out and then locating the position of each of the plurality of classes and the position of the unknown event in the coordinate system in accordance with their respective selected property values. Thereafter, the vector distances from the position of the unknown event to each of the class positions are determined and compared with one another to identify the class which is the shortest vector distance from the unknown event. That class will have selected property values which are, collectively, most similar to those of the unknown event and, accordingly, will be the class with which the unknown event will be designated. The system is also provided with several additional features including a ''''self-training'''' capability and the ability to recognize ambiguities due to system noise to enable other significant information to be obtained relative to the designation operation. The system provided can be utilized to perform essentially any type of designation or classification activity in a rapid and efficient manner.

Abstract: The present invention relates to a system for hue evaluation to be used with reading devices for example in identifying colour rings on ampoules or on packages. Three photoelectric receivers are utilized, each of which receives one of the three primary colours of the hue to be evaluated, and supplies to an evaluating circuit an electric signal corresponding to the proportion of the respective primary colour in the hue, the evaluating circuit forming from the three signals a hue output signal characteristic of the hue. The invention further provides for the primary colour signals to be applied to a maximum formation stage the output of which serves as a reference signal for the primary colour signals.

Abstract: A given scene such as that retained by a colored photograph is scanned both by a high resolution scanner that detects image density gradients and a color analyzer with lower resolution. Controlled by the gradient detecting scanner is a printer that produces, on an appropriate work surface, a line drawing delineating prominent object boundaries in the image. The color information extracted from discrete areas of the image by the color analyzer is compared by a computer with colors available in a preselected finite set of distinctly colored substances and an appropriate selection is made from the set for each area analyzed. In response to the computer selections, a color indicia printer produces on the work surface a color outline of surface areas geometrically corresponding in position to the discrete areas of the image. The color outline is superimposed on the line drawing but is distinguishable therefrom. Also produced by the color printer within each surface area is indicia representing the particular colored substance selected for application thereto. In a preferred embodiment, the density gradient and color analyzer scans are made simultaneously in parallel adjacent paths across the image. The line printer responds instantaneously to the output of the high resolution gradient detector. The color analyzer, however, supplies information at intervals along the scan and the color indicia printer prints on each scan line information from the preceding scan line and in a position corresponding to the area from which the information was obtained. The delay in color indicia printout provides time for color evaluation by the computer.
