    摘要: A first illumination section radiates light at a certain degree of illuminance toward the face of a human recognition object from an upper right part or an upper left part of a camera, and a second illumination section radiates light at a certain degree of illuminance toward the face of the human recognition object from a lower part of a camera. The camera photographs and inputs a facial image of the human recognition object. The image processing section extracts a feature value of the face of the human recognition object from a facial image inputted by the camera and collates the feature value extracted with a standard feature value registered in advance so as to recognize a facial image of the human recognition object.

    摘要: An area information storage section stores positional information on at least two target areas on the standard image of printed matter to be examined, the area of each of the target areas, their standard average densities, and the standard deviation of their density distribution. An average density computing section calculates the average density for each target area in the image data supplied from the image input section using positional information on each target area and its area supplied from the area information storage section. A density difference measuring means measures, target area by target area, the density difference between the average density and the standard average density supplied from the area information storage section. A density difference normalizing section normalizes the density difference and the standard deviation of the density distribution supplied from the area information storage section. On the basis of the added value of the normalized density difference for each of the target areas, a summing section judges the degree of stain on the printed matter to be examined.

    摘要: Apparatus and method for identifying the color image of an object. The object's image is digitized and a cut-off portion of the image containing the object is determined. The cut-off portion image data is normalized. Selected pixels of the normalized image are subjected to an averaging process to provide an averaged image containing R, G, and B color components. H, V, and C components of the averaged image data are computed, and their V, c, and d components are computed from the H, V, and C components. A color feature extractor computes from the c and d component data a parameter representative of the object to be identified. This parameter is provided to a memory controller to retrieve from a memory that stores target images one or more images categorized according to the computed parameter. A matching section matches each retrieved target image with the Vcd component data and determines which target image is most similar.
