Abstract: In a feature matching method for recognizing an object in two-dimensional or three-dimensional image data, features in each of which a predetermined attribute in the two-dimensional or three-dimensional image data takes a local maximum and/or minimum are detected, and features existing along edges and line contours from the detected features are excluded. Thereafter, the remaining features are allocated to a plane, some features are selected from the allocated features by using local information, and feature matching for the selected features being set as objects is performed.

Abstract: A plurality of known markers is disposed in a specific district. A marker detection section detects the known markers existing in the image photographed by an image pickup device. A position/orientation relation calculation section identifies the detected known marker to calculate position and orientation relations between the identified known marker and the image pickup device. An associated information obtaining section obtains predetermined information associated with the identified known marker. An information processing section processes the obtained predetermined information based on the calculated position and orientation relations. A display device superimposes and displays the processed information on the photographed image. At least the image pickup device and display device are disposed in a portable information terminal, and the other sections are disposed in a server which can perform radio communication with the portable information terminal.

Abstract: An information presentation method is to photograph an object by use of an image input device and display related information corresponding to the object on the object in a display screen or the periphery of the object in the display screen. The related information of the object is expressed by the contents of expression of a plurality of two-dimensional markers set on the object or the periphery of the object and the plurality of two-dimensional markers correspond to any one of a plurality of information series.

Abstract: Image information is input by an image input unit, a marker is extracted from an image of the input image information by a marker detector, a position of the extracted marker in the image is detected by a position/posture detector, and the difference between indicators extracted from images is judged. At this time, the position/posture detector is provided with a judgment condition based on the position of each marker, as a judgment condition that is at least selectively applied.

Abstract: An information presenting device is constituted by a recognizing and identifying unit for recognizing and identifying each marker within a photographing range of a photographing unit from an image photographed by the photographing unit, an information designating unit for designating information in accordance with information on each marker identified by the identifying unit, and a presentation image generating unit for generating a presentation image in which the information designated by the information designating unit is associated with the image photographed by the photographing unit. And the information on the each marker that is to be identified by the identifying unit is supplied in a data file set separately from the information presenting device.

Abstract: When an image of a subject including a retrieval-source printout (1) is acquired by a digital camera (10), the digital camera (10) extracts a region corresponding to the retrieval-source printout (1) from the acquired image data, extracts a feature value of the extracted region, accesses a storage (20) in which a database capable of retrieval of image data on the basis of the feature value is constructed, and retrieves original image data of the retrieval-source printout (1) from the database on the basis of the extracted feature value.

Abstract: On the basis of image data obtained by image acquisition, a plurality of image data are retrieved from a database (20), which constitutes a total feature value DB, by template matching using an outline template (21). A single or a plurality of images are retrieved from the retrieved plurality of image data by template matching by using a detail template (22) having a narrower region than the outline template (21) and a high resolution.
