摘要: Method of transforming a voxel representation of an N-dimensional object into a computer model containing a cellular space, which is a specific form of graph. An indicator attached to each edge of the cellular space indicates whether a border belongs to an object. This is useful for three-dimensional compression of video sequences and for Internet video sequence search.

摘要: A digital image coding apparatus, generates a representation of spatially filtered images that are obtainable from a common source image by application of spatial filter operations with respective filter bandwidths. The dependence of image information in the filtered images on position in the filtered image and filter bandwidth is represented by information that defines a surface in a space that has at least the position in the filtered image and the filter bandwidth as coordinates. The shape and position of the surface at least partly defines said dependence. The apparatus receives an image signal that represents the source image as a function of position in the image. The apparatus then selects coordinate values of a set of control points. Selection includes selecting filter bandwidth components of the coordinate values, dependent on the image signal. The selection optimizes a quality of approximation by an approximate version of the surface of a true version of the surface that follows from the source image.

摘要: In a method of generating motion blur in a 3D-graphics system, geometrical information (GI) defining a shape of a graphics primitive (GP) is received (RSS; RTS) from a 3D-application. A displacement vector (SDV; TDV) defining a direction of motion of the graphics primitive (GP) is also received from the 3D-application or is determined from the geometrical information. The graphics primitive (GP) is sampled (RSS; RTS) in the direction indicated by the displacement vector to obtain input samples (RPi), and an one dimensional spatial filtering (ODF) is performed on the input samples (RPi) to obtain temporal prefiltering.
