    摘要: An image processing apparatus 10 acquires an image. And, the image processing apparatus 10 extracts a domain characterizing an object of gesture recognition from the acquired image. Then, the image processing apparatus 10 maps domains between frames of the image. And then, the image processing apparatus 10 extracts a moving direction of the domains. And then, the image processing apparatus 10 outputs the moving direction when a moving distance of the domains is greater than a predetermined threshold. And then, the image processing apparatus 10 updates the threshold using a moving distance exceeding the threshold.

    摘要: Upon receiving, for example, document data including a character string from outside, a character recognition device detects a line from a line-touching character-string image in which at least one character (such as number, alphabet letter, kana character, and Chinese character) touches (or overlaps) a line in the document data, tentatively removes the line, and estimates a character region. The character recognition device extracts a line-touching character image from the line-touching character-string image (original image) based on the estimated character region. The character recognition device creates a line-added reference character image by adding a quasi-line to a reference character image stored in advance.

    摘要: A document information input apparatus detects a position and an attribute of an area of a real document to be input designated by a user with high accuracy. Based on the detected position and attribute, the document information input apparatus recognizes an image of the area as text information by performing recognition processes suitable for the detected attribute such as character recognition, table recognition and a figure process. Then, the document information input apparatus pastes the resulting information to a pertinent position of an electronic document on a display. As a result, it is possible to input information such as a character sequence, a table and a figure from a real document to an electronic document at high speed and with high accuracy.

    摘要: An image processing apparatus includes a central-portion extracting unit, a classifying unit and a determining unit. The central-portion extracting unit extracts edges from an image area and extracts a plurality of central portions of areas each of which is sandwiched between the edges. The classifying unit groups the central portions by classifying adjacent central portions that have no edge therebetween into a single group. The determining unit determines an area of finger, the area of finger being surrounded by the central portions classified into a group by the classifying unit and peripheral edges of the central portion, the area of finger being an area where a ratio of a luminance gradient in a short side direction to a luminance gradient in a long side direction is within a predetermined threshold.
