    摘要： A motion image processing method and device for authenticating a user using a specific device, using motion information of an object. Time series monochrome images, obtained by photographing an object, using a camera, are input. An object is detected from an initial frame of the input time series images, using a basic shape characteristic, and a plurality of reference points to be tracked are automatically determined in the object. Then, corresponding points of the respective reference points are detected in an image frame other than the initial frame among the input time series images. Subsequently, motion information of a finger is calculated, based on the result of tracking the respective reference points and an assumption of limited motion in a 3D plane. Based on the calculated motion parameter, a solid object is subjected to coordinate conversion, and displayed if necessary. As a result of the tracking, a reference point in each frame is updated. Tracking, motion parameter calculation, and displaying are repeated with respect to subsequent frames.

    摘要： The present method represents a three-dimensional shape model by polygons according to a plurality of object images information picked up by rotating a real object for every arbitrary angle to assign texture information on each polygon from object image information having the largest projection area of the relevant polygon. In order to improve the color continuity between adjacent polygons, the object image information having correspondence between a polygon of interest and an adjacent polygon thereof is selected so as to be the object image information approximating the shooting position and the shooting direction. An alternative method divides an object image into a plurality of regions, obtains difference between an object image and a background image in region level, outputs a mean value of the absolute value of difference in the region level, and detects the region having the mean value of absolute values of difference equal to or greater than a threshold value as the object portion. Another further method obtains a plurality of object images by shooting only a background of an object of interest and by shooting the object of interest during each rotation. A silhouette image is generated by carrying out a difference process between the object image and the background image. A voting process is carried out on the voxel space on the basis of the silhouette image. A polygon is generated according to the three-dimensional shape obtained by the voting process. The texture obtained from the object image is mapped to the polygon.

    摘要： A reference sheet is employed on which reference points are arranged irregularly and asymmetrically. An object of interest is placed on the reference sheet. The object of interest is shot together with the reference points by a camera. A shooting position of the camera is calculated according to the Hough transform method on the basis of the position of a reference point in the obtained object image. A three-dimensional model is generated according to the obtained object image and shooting position. Therefore, a simple and economic three-dimensional modeling apparatus that does not require a turntable can be provided.

    摘要： An image processing method for matching edges detected in images of the same objects in a three-dimensional scene which are taken simultaneously by two or more image pick-up devices at different positions, in which the boundary segments on the edges are classified into apparently real segments, apparently imaginary segments or undefined segments, a planar surface is found for each boundary which has all apparently real segments and no apparently imaginary segment on it by using the information of the points of occlusion, the surface is regarded as the real surface in the case where there is only one surface which has no segment under it, so that surface information and the distance information at arbitrary points on the real surface are obtained.
