  • Patent number: 6751605
    Abstract: A character recognition apparatus for inferring the entire character string solely from a user-input handwritten keyword and displaying the inferred result as a candidate character string. The apparatus of the invention comprises: a word string includes a word hierarchy and for recognizing each of the words within the hierarchy; a character transition probability table a4 storing probabilities of transitions from any one character to another, and those pieces of the word identification information which correspond to combinations of characters resulting from the transitions; and an optimization unit for using the character transition probability table in optimizing candidate character strings obtained by a recognition unit. The word dictionary is searched for a word defined by the word identification information which corresponds to the optimized candidate character string, whereby the searched word is retrieved which applies to the hierarchy information and which has yet to be input.

  • Patent number: 6718060
    Abstract: A character recognizing apparatus capable of recognizing discriminatively characters written continuously, irregularly and/or containing modification is provided which apparatus includes an input unit for allowing a handwritten character to be inputted to thereby output coordinate-points string, a dictionary for storing therein a plurality of character codes and character patterns corresponding to the character codes, respectively, an element decomposition module for decomposing the coordinates string outputted from the input unit into a plurality of elements which constitute the character, and a matching module for determining corresponding distance values for the elements of the character pattern stored in the dictionary and the elements of character pattern of the inputted character for each of the character patterns stored in the dictionary, to thereby correct the distance values determined on the basis of the elements bearing no correspondence.

  • Patent number: 6385339
    Abstract: The present invention relates to a multi-user pattern data processing system configured for various kinds of patterns, such as characters, to learn efficiently and effectively. The present invention comprises an input arrangement 1 having patterns entered therein from a plurality of users, a dictionary 2 having patterns and attributes of the patterns belonging thereto defined therein, a recognizing arrangement 4 that receives the entered pattern and a group attribute and retrieves from among the patterns entered in the dictionary and having a corresponding group attribute to feed out the category, and a dictionary editing arrangement 5 for extracting a pattern used in common by a group before editing the pattern, such as entering it in the common dictionary, with the group having the user made to belong thereto. The invention allows the dictionary used to the pattern recognition to learn very efficiently and effectively.

  • Patent number: 6369805
    Abstract: The present invention relates to an information processing system using a coordinate detection device and displays, and more specifically to an input-display integrated information processing system which allows the displays to be carried like paper and to be freely laid out and stacked together on a desk (coordinate input device). The system includes a layout determining unit for determining a layout of the display on said coordinate detection device, wherein the layout determining unit further comprises a display position coordinate detector that detects where in the coordinate space of the coordinate detection device the display for displaying an information is located, and a coordinate converter that converts the information into display coordinates. The layout determination is done by using markers attached to three of the four corners of the display.

  • Patent number: 6097841
    Abstract: A character recognition apparatus for inferring the entire character string solely from a user-input handwritten keyword and displaying the inferred result as a candidate character string. The apparatus of the invention comprises: a word dictionary storing word identification information and hierarchy information for layering a plurality of words into a hierarchy and for recognizing each of the words within the hierarchy; a character transition probability table a4 storing probabilities of transitions from any one character to another, and those pieces of the word identification information which correspond to combinations of characters resulting from the transitions; and an optimization unit for using the character transition probability table in optimizing candidate character strings obtained by a recognition unit.
