  • Patent number: 7092563
    Abstract: There are performed three types of object shooting, i.e., a projection pattern shooting using a pattern including both characterization of a stripe based on a color and characterization based on a gradation of the same component, a flash shooting without a pattern and a non-flash shooting without a pattern. A two-dimensional image information generation portion corrects the influence of a surface reflectivity of an object or external light from the three types of images, and estimates a pattern structure using the characteristic based on a color with respect to an object having a white-based color or a low-saturation color and based on a gradation with respect to an object having a high-saturation color. A depth calculation portion specifies the correspondence relationship between the estimated pattern structure and information of the projected pattern, and calculates a depth of each part of the object based on a result of specification.

  • Patent number: 7072514
    Abstract: The present invention is a method of categorizing an image as handwritten, machine-printed, and unknown. First, the image is received. Next, connected components are identified. Next, a bounding box encloses each connected component. Next, a height and width is computed for each bounding box. Next, a sum and maximum horizontal run for each connected component are computed. Next, connected components that are suspected of being characters are identified. If the number of suspected characters is less than or equal to a first user-definable number then the image is categorized as unknown. If the number of suspected characters is greater than the first user-definable number then determine if matches exist amongst the suspected characters. Next, compute a score based on the suspected characters and the number of matches and categorize the image as either handwritten, machine-printed, or unknown.

  • Patent number: 7058238
    Abstract: A current frame portion (21) stores therein the most recent information of an image of those fingerprint images input from an inputted unit (1), while a previous frame portion (22) stores therein image information saved in the current frame portion (21). A pixel comparing portion (31) compares mutually corresponding pixel gray-level value information saved in the current frame portion (21) and the previous frame portion (22) respectively. A gray-level-value-changed pixels counting portion (32) counts the gray-level-value-increased pixels and the gray-level-value-decreased pixels based on the resultant information of that comparison of the pixel gray-level values. A pick-up timing deciding portion (33) utilizes the results obtained by the gray-level-value-changed pixels counting portion (32), to automatically detect a fingerprint image appropriate for matching in order to thus decide pick-up timing and also in order to output to an output unit (4) an appropriate fingerprint image based on the decision results.

  • Patent number: 7058223
    Abstract: A system is described for linking traditional media works, such as print and broadcast media for example, to a more interactive media conduit, such as the Internet. The system avoids the need to modify the media work in anyway. Instead, it employs a passive recognition system that uniquely identifies the specific work, such as a particular television or radio broadcast or printed commercial. The identification may be based in intra-work and/or extra-work information. Several different embodiments/environments are described. The best embodiment may depend, at least in part, on costs of hardware and communication. These costs can change over time. In one embodiment, all of the databases and computation are performed at the user's premises. In another embodiment, all of the databases and computation occur at remote sites that user premise equipment can query using uniquely identifying extra-work information, such as the time, place and station on which the work was broadcast.

  • Patent number: 7031526
    Abstract: The invention improves the appearance of freehand drawn lines and shapes in an electronic document by first recognizing freehand drawn lines and shapes and generating a line made up of sequential straight line segments for the freehand drawn line when the line does not form a closed line and generating a multiple straight-line-segment shape when the line forms a closed line. If a multiple segment shape is being reshaped, a basic shape is selected from reference ideal shapes as the basic shape of the multiple segment shape. The basic shape is adjusted to provide a specific shape as an improved shape for the freehand drawn shape. The recognition of the freehand drawn lines and shapes is accomplished by comparing source segments of a source freehand drawn line to a straight line and substituting a straight line segment for a source segment if the deviation between the source segment and the straight line is below a predetermined value.

  • Patent number: 7027616
    Abstract: In transmitting image data from multiple cameras to an image processing section to produce a synthesized image from respective camera images, the amount of data transmitted through a transmission path can be cut down without sacrificing the quality of the synthesized image. In accordance with a correspondence between the synthesized and camera images as described on a mapping table, a resolution specifier specifies resolutions, which should be necessary for image synthesis, for respective areas of each camera image. A compressor, provided for each of the cameras, compresses the associated camera image data according to the resolutions specified. In this manner, the image data, which has been compressed in accordance with the correspondence between the synthesized and camera images, is transmitted through the transmission path.

  • Patent number: 7024042
    Abstract: The capacity of a character feature dictionary is reduced, and stored as a feature dictionary. The capacity is reduced by clustering feature vectors in units of columns or rows for character features, by making m column vectors represent the column or row features, and by assigning 1 to m identification numbers. The capacity of the dictionary can be further reduced by representing a column or row feature with an addition sum of other column or row features, or differential features after clustering is performed, or by performing dimension compression for character features. Word recognition is performed by synthesizing a word feature for a comparison based on a word list to be recognized, and by making a comparison between a feature extracted from an input word and the synthesized feature. Or, a comparison between input word and input word features whose numbers of dimensions are different may be made with nonlinear elastic matching.
