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.

There provides an apparatus for and a method of generating a classifier for detecting a specific object in an image. The apparatus for generating a classifier for detecting a specific object in an image includes: a region dividing section for dividing, from a sample image, at least one square region having a side length equal to or shorter than the length of shorter side of the sample image; a feature extracting section for extracting an image feature from at least a part of the square regions divided by the region dividing section; and a training section for performing training based on the extracted image feature to generate a classifier. By using the apparatus for and method of generating the classifier, it becomes possible to make full use of recognizable regions of objects to be recognized with variable aspect ratios and improve speed and accuracy for recognizing in complex backgrounds.

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.

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.

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.

A pattern segmentation apparatus and a pattern recognition apparatus can improve the segmentation precision of a character touching pattern. The pattern segmentation apparatus includes a feature amount extraction unit for extracting the feature amount of an image, a feature amount setting unit for setting the feature amount of a category, a feature amount comparison unit for comparing the feature amount of the category with the feature amount of the image, and a segmentation unit for segmenting a portion corresponding to the feature amount of the category from the image based on the comparison result.

A word recognizing apparatus extracts the feature amount from a given image, and dynamically composes the feature amount of a candidate word to be recognized which is registered in a word list, using feature amounts of characters registered in an individual character dictionary. Then, the apparatus collates the composed feature amount of the word with the feature amount extracted from the image, calculates the degree of similarity between the two feature amounts, and outputs a recognition result.
