摘要:
A plurality of background texture patterns each of which includes a region not having a dot and having a feature different from those of the other background texture patterns, are combined, and information is embedded in a background region of a document image. Then, a mathematical-morphology-based conversion is performed on the document image, and thereby a feature of a region not having a dot in each of the background texture patterns is extracted in order to identify the embedded information.
摘要:
A block where basic units of a background pattern are arranged two-dimensionally is formed so as to stably read buried information from a printed background pattern. Binary or multivalued number is assigned to the block to express information. When a binary number (bit) is assigned to a block made up of background patterns in double size, error correction can be made if an error occurs only in one background pattern while reading the block. In each background pattern, a diagonal lacking its center part is drawn, and isolated dots are placed along the other diagonal. With this, while ensuring the stability of reading the buried information after the read by a scanner, the uniformness of appearance of the printed object can be ensured.

摘要:
An embedding area in which a background pattern can be embedded from the color document image is extracted. At least one of a color and a shape of a background pattern appropriate for the embedding area is determined depending on an area color of the embedding area. A background pattern image is generated by embedding watermark information in the embedding area using the determined background pattern.

In an image determining apparatus, a subject-shape presuming unit extracts a shape of a specified subject to be determined based on subject-area position information and structure/surface-height map information, a subject-feature-point extracting unit extracts a feature point based on the shape of the subject to be determined. Further, an other-object-influence determining unit generates number information based on camera data, the feature point, and the height of a group of surrounding objects, an other-object-influence index calculator calculates an other-object-influence index based on the number information, and a display processor displays video picture data based on the other-object-influence index on a display device.

In a synchronized contents information generating apparatus, a keyword extractor extracts a characteristic keyword from document information whose document is an electronic document, and an audio analyzer measures a keyword appearance distribution in the order in which the extracted each keyword appears based on audio/video information that is audio and video, recorded by a video camera unit, of how a meeting using the document goes on. A synchronized contents information generator generates synchronized contents information used to display the document information in synchronization with the audio/video information based on the keyword appearance distribution.

A video management system comprises a calculating unit calculating, with respect to each of a plurality of size orders, a minimum bounding region (MBR) embracing a view volume that defines a range to be shot in real space based on pieces of data representing a shooting position and a shooting direction of a video, and a management unit storing, as data representing a shooting range of a video being a management target, data representing the MBR corresponding to each of the plurality of size orders calculated, in a storage.
