摘要： Silicon carbide single crystal is produced by allowing a silicon raw material to continuously react with a carbon raw material to generate gas, which reaches a seed crystal substrate on which a silicon carbide single crystal grows. Preferably, the silicon raw material is continuously fed onto the carbon raw material placed in a reaction crucible, and the carbon raw material is maintained at a temperature such that carbon is allowed to react with silicon in a molten state or a gaseous state to generate the reaction gas. An apparatus used for producing the silicon carbide single crystal comprises a reaction crucible, and a seed crystal substrate disposed in the reaction crucible; and further comprises means for maintaining the carbon raw material placed in the reaction crucible at a temperature such that carbon is allowed to react with silicon in a molten state or a gaseous state to generate the reaction gas, and means for continuously feeding the silicon raw material onto the carbon raw material placed in the reaction crucible.

摘要： This invention provides a matching point extracting method and an apparatus therefor, for extracting the matching points among plural images based on the template matching method. The method consists of forming mutually different plural templates from an arbitrary one of plural images, and determining the matching points in the plural images, in an image area showing a specified condition, by utilizing one of thus formed plural templates, thereby enabling highly prescise extraction of the matching points over the entire image area, without difference between the object and the background in the image.

摘要： In a three-dimensional shape extraction apparatus, a distance distribution extraction unit (54) obtains the distance distribution of an object on the basis of a plurality of images which are sensed by a camera at different image sensing positions, so that the images of the object partially overlap each other, and the position information of the respective image sensing positions of the camera. A three-dimensional model forming unit (55) forms a three-dimensional model of the object by sequentially combining the sequentially calculated distance distributions and the sensed images using the position information. A 3D display image generation unit (56) generates and displays a two-dimensional image from the three-dimensional model.

摘要： An image combine apparatus for combining a plurality of images to generate a panoramic image. The image combine apparatus identifies an overlapping region of two inputted images and determines a boundary of the two images. The image combine apparatus then sets a tone correction area having a predetermined width such that the boundary of the two images is the center of the area, and performs tone correction within the area. The image combine apparatus performs linear tone correction in accordance with a distance between a pixel and the boundary. In the neighbor of the boundary of the two images within the tone correction area, density of the image gradually changes, thus a combined image whose boundary of the two images is inconspicuous is obtained.

摘要： There is provided an information processing apparatus for detecting a foreground portion from an acquired image. Feature-amount information of a past acquired image and likelihood information indicating a probability that a subject is represented is stored as background-model information. A foreground region is detected based on the likelihood information and a result of comparing the feature amount extracted from the acquired image with the feature-amount information contained in the background-model information. For each of the detected foreground region, a likelihood indicating a probability that the region represents the subject is calculated based on information prepared in advance related to the subject.
