Abstract: A memory based computer graphic animation system generates desired images and image sequences from 2-D views. The 2-D views provide sparse data from which intermediate views are generated based on a generalization and interpolation technique of the invention. This technique is called a Hyper Basis function network and provides a smooth mapping between the given set of 2-D views and a resulting image sequence for animating a subject in a desired movement. A multilayer network provides learning of such mappings and is based on Hyper Basis Functions (HBF's). A special case of the HBFs is the radial basis function technique used in a preferred embodiment. The invention generalization/integration technique involves establishing working axes along which different views of the subject are taken. Different points along the working axes define different positions (geometrical and/or graphical) of the subject.

Abstract: The invention method and apparatus employs font metrics data related to font bitmaps for characters of a desired font. Position offsets of pieces in composite characters are read from the font metrics data and are converted to the appropriate pixel offset to adjust the bitmaps of subject compressed font characters. The adjusted bitmaps of the different pieces of a subject composite character are combined to form a working bitmap which represents each piece of the composite character in full size in the subject font. Screen display of composite characters decompressed to full-size is supported by the formed working bitmaps.
Abstract: A document processor which advantageously provides usage information for words includes a first memory for storing a document to be elaborated, the document including first word data, a second memory for storing a dictionary including second word data and usage data associated with the second word data, and a third memory for temporarily storing a list of third word data which are not to be elaborated. A controller sequentially retrieves the first word data included in the first memory, sequentially compares the first word data with the second word data and the third word data, and selects individual word data for elaboration from the first word data which coincides with the second word data and which does not coincide with the third word data.
Abstract: The system for generating dot signals corresponding to a character pattern on the basis of outline information of a character pattern described by only straight lines comprises a section 6 for deciding end points of straight lines constituting outlines on the basis of the outline information. In response to end point information decided by this section 6, a DDA calculating section 7 continuously generates information indicative of a pair of points constituting two straight lines, respectively in such a way that two straight lines can be extended from one end point selected from the decided end points toward two end points adjacent thereto. The generated information indicative of a pair of points is inputted to a straight line generating section 8 for generating a straight line composed of dot signals between a pair of the points. These dot signals correspond to a character pattern.
Abstract: A computer system user interface that includes a method of accessing electronic data. The method includes displaying on a computer display screen a control window that includes a perspective view of a work area. The work area includes at least one animated icon that is movable from a closed position to a substantial continuum of open positions. Moving the icon to an open position automatically opens a window on the display screen that contains the data to be accessed. Closing the icon automatically closes the window.
