  • Patent number: 6643407
    Abstract: The method of compressing a multi-spectral image formed of a plurality of elemental images having different spectral distribution ranges calculates an average image and a superior average image by averaging two elemental images and two inferior average images having respective spectral distribution ranges close to each other, respectively. The method calculates finally a superlative average image of all the elemental images by hierarchically repeating the calculating step. Next, the method creates differential images between all the elemental images and the respective average images and between the inferior average images and the respective superior average and calculates compressed differential images by compressing the differential images. The method records the superlative average image and the compressed differential images so as to take a hierarchical structure with the superlative average image being positioned at a top.

  • Patent number: 6636631
    Abstract: A method of recognizing characters of a document including ruled lines. After separating the characters from the ruled lines, a bounding box and a corresponding character pattern are extracted for each character (hereinafter, “the character”). Contour information and ground (white pel area) information are extracted as fundamental features from the character pattern. Various statistical features are extracted based on the fundamental features. Various structural features are extracted based on the fundamental features and the character pattern. On the basis of the extracted statistical features, some candidates for the character and corresponding degrees of similarity are found to provide at least such one of the candidates as has largest degree(s) of similarity and degree(s) of similarity associated with the provided candidate(s).

  • Patent number: 5966701
    Abstract: A fuzzy rough classification section 7 classifies an input pattern into a plurality of category groups and calculates their attribution factors. A plurality of fine classification sections 8 calculate similarities in respective category groups. In each fine classification section 8, a weight change amount control section 82 controls the weight change amount in an associated similarity calculating section 81 in accordance with the group attribution factor selected by a second group selecting section (10), thereby enabling a cooperative learning operation among plural fine classification sections 8. A force learning control section 17 performs a supplemental learning operation, if the input pattern is rejected regardless of its correctness, until its reject judge value is reduced below a predetermined reject threshold.
