摘要： A search apparatus searches for a keyword from a character recognition result using an index table. The character recognition result being obtained as a result of character recognition of characters in an original document. The index table includes an index character string; a position of a portion, in the character recognition result, which matches the index character string; and a credibility which is defined for each character included in the index character string and indicates a probability of the character existing in a portion, in the original document, which corresponds to a portion, in the character recognition result, which matches the character. The search apparatus includes a position specifying section for determining whether or not the keyword matches a portion in the character recognition result based on the index character string and the position of the portion in the character recognition result which matches the index character string included in the index table; and when a match is determined, for specifying the position of the portion in the character recognition result which matches the keyword; and a calculation section for calculating a keyword credibility which indicates a probability of the keyword existing at a position, in the original document, which corresponds to the position of the portion in the character recognition result which matches the keyword, based on the credibility included in the index table.

摘要： A document search device searches for a keyword in a recognition result obtained by character recognition performed on a document image. The keyword includes at least one first character, and a character code is assigned to each of the at least one first character. The recognition result includes at least one second character, and a character code and a partial area of the document image are assigned to each of the at least one second character. The document search device includes a first matching portion specification section for determining whether or not the recognition result includes at least one first matching portion which matches the keyword based on a comparison of the character codes, and for, when it is included, specifying the at least one first matching portion; a first portion specification section for determining whether or not a remaining part of the recognition result other than the at least one first matching portion includes at least one first portion which fulfills a prescribed first condition, and for, when it is include, specifying the at least first portion; and a second matching portion specification section for determining whether or not the at least one first portion includes at least one second matching portion which matches the keyword based on a comparison of a feature amount of the partial area with a feature amount of an image of at least one first character included in the keyword, and for, when it is included, specifying the at least one second matching portion. The prescribed first condition includes a condition that the at least one first portion is in the vicinity of a specific second character having a width smaller than a prescribed value.

摘要： The present invention relates to a retrieval method for searching a first character element string obtained by subjecting a character string to character recognition for a second character element string. The first character element string includes a first character element and the second character element string includes a second character element. A distance relevant to a similarity between the first character element and the second character element is predetermined between the first character element and the second character element. The retrieval method comprises the steps of comparing the distance with a predetermined reference distance, and determining whether the second character element matches the first character element based on a result of the comparison of the distance with the predetermined reference distance.

摘要： An image coding apparatus includes an image feature extraction means for generating character data which includes character codes corresponding to character images included in a document image and auxiliary information indicating the sizes and positions of the respective character images in the document image based on image data indicating the document image. The image coding apparatus generates a predictive document image for the document image based on the character data, and subjects the document image data to arithmetic coding in which the probability model is changed with reference to predictive document image data. In the image coding apparatus, the probabilities of white pixels and black pixels indicated by the probability model are very close to those in the character image, whereby the coding efficiency for the character image data in the arithmetic encoder is improved.

摘要： A manipulator includes a main unit movable to a specified target position, an arm unit rotatably provided on the main unit, and a posture controller. The posture controller controls the posture of the arm unit so that a front surface of the arm unit facing forward in a moving direction of the main unit is not orthogonal to the moving direction of the main unit when the movement of the main unit is performed. The arm unit may be inclined obliquely backward with respect to a moving direction of the main unit when the main unit is moved to a specified target position.

摘要： A sensing unit, such as a camera, or the like, senses the conditions of articles and mobile existences, including humans, in a life space, such as a house of a household, or the like. An article management/operation server manages, on an article database, attribute information of the articles, which include operators, etc., according to the information from the sensing unit. The server receives a user's instruction input through a console unit and refers to the article database to convert this instruction to a control command, which is then transmitted to a life-support robot.
