    摘要： An image recognition apparatus recognizes the correspondence between character strings and logical elements composing a logical structure in an image in which the character strings are described as the logical elements to recognize each logical element. The image recognition apparatus includes outputting means for outputting the recognized logical elements when the correspondence is recognized or re-recognized; first determining means for determining a certain logical element to be correct when input of a determination request to determine the logical element is received from a user; second determining means for determining the correctness of all the logical elements output before the logical element determined by the first determining means and is positioned according to confirmation by the user; and re-recognizing means for re-recognizing the correspondence between logical elements that have not been determined to be correct and the character strings on the basis of the determination content for each logical element.

    摘要： In an apparatus for analyzing a layout of a document, a character candidate element generator generates character candidate elements from black pixel linkage components of a document image. A horizontally oriented line rectangle generator sets a plurality of character candidate elements as a line candidate rectangle, among character candidate elements aligned in horizontal line orientation, when each amount of displacement of the set character candidate elements in a vertical orientation with respect to the horizontal line orientation, is smaller than or equal to a threshold value. A horizontally oriented paragraph-box generator sets a plurality of line candidate elements having approximately the same length as each other in the vertical orientation, as a paragraph candidate element.
