Abstract: A computer-implemented method for estimating a size of a foot comprising: receiving a plurality of images of the foot in relation to a sheet of paper; performing determination of a contour of the sheet of paper in the received plurality of images; using at least one of the received plurality of images to determine an internal contour of the foot; using at least second one of the received plurality of images to determine an external contour of the foot; using the determined internal contour of the foot and the determined external contour of the foot to calculate a horizontal contour of the foot and calculate a size of the horizontal contour of the foot; and using at least third one of the received plurality of images to determine an vertical contour of the foot and calculate a sizes of the vertical contour of the foot.

Abstract: An apparatus and method for reconstructing 3D graphics data is provided. The apparatus includes a parsing unit to parse 3D graphics data, an aligning unit to align objects of a scene graph having nodes storing geometric information and material information that corresponds to the geometric information included in the 3D graphics data parsed by the parsing unit and hierarchy information regarding the nodes, using predetermined detail information of the material information as a reference, and a rendering unit to interpret the objects of the scene graph aligned by the aligning unit to convert the 3D graphics data into 2D graphics data. Therefore, the present invention can omit the operation of repeatedly storing the same material information by classifying each node of the scene graph according to the material information.
