20080212837 | LICENSE PLATE RECOGNITION APPARATUS, LICENSE PLATE RECOGNITION METHOD, AND COMPUTER-READABLE STORAGE MEDIUM - A license plate recognition apparatus includes a detection unit configured to detect a plurality of quadrangles of license plate region candidates from input images, a character recognition unit configured to execute character recognition of a character region included in the license plate region candidate detected, and an output unit configured to select a license plate region candidate to be output from among the plurality of license plate candidates detected by the detection unit based on the character recognition result and information of the quadrangle of the respective license plate region candidates and output information relating to the license plate region candidates selected. | 09-04-2008 |
20090121024 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM STORED IN STORAGE MEDIUM - When a two-dimensional code including a number of location symbols is detected from an image. First, a plurality of location symbols are detected from the image. Then, candidate location symbols are determined among the detected location symbols on the basis of sizes of the detected location symbols and distances between the detected location symbols. After that, a combination of location symbols constituting the two-dimensional code is detected among the candidate location symbols. | 05-14-2009 |
20090297027 | ELECTRONIC DOCUMENT PRODUCING DEVICE, ELECTRONIC DOCUMENT PRODUCING METHOD AND STORAGE MEDIUM - An electronic document producing device has a correcting unit for correcting distortion of a first image to obtain a correction image, and a character recognition unit for executing character recognition processing on a plurality of character images contained in the correction image to obtain text data. The device also has a unit for finding a base line of each character row in the first image, and a unit for finding a relative position from the base line in regard to each character image in the first image. The device also includes a producing unit for producing an electronic document including the text data and the first image, wherein a position of the text data is described based on the relative position from the base line. | 12-03-2009 |
20100014752 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND PROGRAM - A problem of the present invention is to generate the vector expression for expressing dark and light or blur of characters or figures of which the direction or the dark and light of the gradation changes unevenly. | 01-21-2010 |
20100074546 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND MEDIUM STORING IMAGE PROCESSING PROGRAM - A reflectance image that represents a reflectance distribution, and an illuminance component image that represents an illuminance distribution are generated from an input image. A plurality of small regions, which are divided based on illuminance components of the generated illuminance component image, are specified. A quantized image is generated from the reflectance image for respective specified small regions. Regions having equal quantized pixel values are acquired in the quantized image. Representative pixel values for the respective acquired regions are acquired based on the illuminance component image. Quantized pixel values of the respective acquired regions are corrected using the acquired representative pixel values. | 03-25-2010 |
20110091097 | APPARATUS OF LEARNING RECOGNITION DICTIONARY, AND METHOD OF LEARNING RECOGNITION DICTIONARY - There are provided a characteristic obtaining unit configured to obtain a subject characteristic including a characteristic of a subject, an image processing unit configured to generate a duplicate subject image by performing an image process to an image of the subject according to the subject characteristic obtained by the characteristic obtaining unit, and a learning unit configured to learn a matching dictionary by using the duplicate subject image generated by the image processing unit. Thus, it is possible to reduce the number of subject images necessary for the learning. | 04-21-2011 |
20140140583 | IMAGE RECOGNITION APPARATUS AND IMAGE RECOGNITION METHOD FOR IDENTIFYING OBJECT - There are provided an image recognition apparatus and an image recognition method according to which, when registering a face model for a face image, face images are sequentially acquired from frames of a moving image, feature amounts are extracted from the sequentially acquired face images, and a hypersphere defined by Support Vector Data Description (SVDD) is obtained from the group of training samples. Then, training samples in a boundary region of the hypersphere are registered as boundary samples. When performing matching of a face image of a recognition target, the reliability is calculated using the boundary samples, and a person with the highest reliability is output as a recognition result. | 05-22-2014 |
20150138386 | OBJECT DETECTING APPARATUS AND METHOD - An image processing apparatus comprises: an image acquiring unit to acquire an image including an object; a dividing unit to divide the image, which is acquired by the image acquiring unit, into a plurality of superpixels based on similarity of adjacent pixels; a candidate area acquiring unit to acquire, from the superpixels divided by the dividing unit, a plurality of candidate areas acting as candidates of an area of the object; an extracting unit to extract a feature quantity from each of the plurality of candidate areas acquired by the candidate area acquiring unit; a checking unit to check the feature quantity, which is extracted from each candidate area by the extracting unit, against registered information concerning a feature quantity of object area; and an outputting unit to output the area of the object in the image, based on a checked result by the checking unit. | 05-21-2015 |
