[PROBLEMS TO BE SOLVED] It is an object to provide a marker and a marker generating and detecting technology that can automatically design a diagrammatic marker that is not similar to any patterns to appear during the reproduction of background video images. [MEANS FOR SOLVING THE PROBLEMS] A marker generating system is characterized in having a special feature extracting means that extracts a portion, as a special feature, including a distinctive pattern in a video image not including a marker; a unique special feature selecting means that, based on the extracted special feature, selects a special feature of an image, as a unique special feature, that does not appear on the video image; and a marker generating means that generates a marker based on the unique special feature.

Marker generating and marker detecting system, method and program

Provided is a marker generation device which has a measurement means, an invariant feature conversion means, a singular feature selection means, and a marker generation means. The measurement means measures a change in posture of an object in a background image on the basis of the image. The invariant feature conversion means indicates feature points extracted from the background image in an invariant feature space by means of a predetermined conversion process in accordance with the change in posture. The singular feature selection means selects, as a singular feature, a part in which the feature points are not indicated in the invariant feature space. The marker generation means generates a marker with the use of the singular feature.

Provided is a marker judgment device which has a feature storage means and a feature comparison means. The feature storage means disposes feature points extracted from an image in a predetermined space, sets parts in which the number of feature points in the predetermined space is equal to or less than a predetermined number as singular features, and stores the singular features and feature points extracted from an existing mark. The feature comparison means disposes the feature points extracted from the existing mark in the predetermined space, and judges that the existing mark is capable of being used as a marker which is detectable from the image, when the number of feature points that coincide with the singular features is equal to or more than a predetermined number.

Provided is a marker generation device which has a feature comparison means and a marker pattern generation means. The feature comparison means disposes feature points extracted from an image in a predetermined space, sets parts in which the number of feature points in the predetermined space is equal to or less than a predetermined number as singular features, disposes feature points extracted from an identifier in the predetermined space, and counts the number of feature points that coincide with the singular features. The marker pattern generation means converts the structure of the identifier and extracts the feature points from the converted identifier. The feature comparison means disposes the feature points extracted from the converted identifier in the predetermined space, counts the number of feature points that coincide with the singular features, and selects, as a marker for detection, an identifier having the most counts from among identifiers before conversion and one or two or more identifiers that have been converted.

Image combining system, image combining method, and program

A capture devicefirst captures the whole of a documentand thereby obtains a total image of the documentA structure analysis sectionconducts image structure analysis to the total image, and thereby extracts structural elements (text, figure, picture, etc.) of the documentand obtains position information of the structural elements. For each of one or more selected structural elements, a sub-image acquisition process is conducted, in which a control information generation sectiondetermines one or more partial areas and a resolution to be used for capturing the selected structural element and an image acquisition control sectionacquires sub-images of the partial areas of the structural element by use of the capture devicewith the determined resolution. An image connection sectionconnects the sub-images together and thereby obtains a high resolution image (synthesis target image) of the structural element. For each of the other (not selected) structural elements to which the sub-image acquisition process has not been conducted, part of the total image corresponding to the structural element is extracted as a synthesis target image. An image reconstruction sectionsynthesizes the synthesis target images of the structural elements maintaining relative position relationship between the structural elements, thereby a wide-area high-resolution image of the documentis obtained even if relatively large blank areas existed in the document
