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: An integrated, multisensory recognition (identification and verification) system is described. Acoustic features and visual features are integrated in order to identify people or to verify their identities. The integration of the speaker-identification and visual-features-identification functions improves both performance and reliability in the applications envisaged. Various architectures are described for the implementation both of the integration function and of the speaker-recognition and visual-features-recognition functions.

Abstract: Computer apparatus and method determines correspondence between two shapes or drawings. Included is a computer matcher which determines point by point matches/correspondence between a source object or drawing and a target object or drawing. As applied to the generation of animation sequences, the computer matcher is given as input a source drawing, a target drawing and at least four working points on the first drawing matched to four working points on the second drawing. The matcher defines a transform vector from the initially given working points of the first drawing and working points of the second drawing and their association. With the transform vector, the matcher performs a vector transformation of each of the remaining points on the first drawing to a respective point on the second drawing. This generates a correspondence and thus match between remaining points on the first drawing with respective remaining points on the second drawing.

Abstract: A sensing device for generating an output signal corresponding to an input signal which comprises a substrate, an array of sensor elements for receiving the input signal and transfer members located on the surface of the substrate and interposed between the sensor elements. The sensor elements have their barycenters distributed on the surface of the substrate in a random non-periodic pattern. The transfer members are coupled to the sensor elements and generate the output signal.The sensing device is incorporated in an apparatus which generates an output signal from an input image wherein the output signal is substantially free of detectable aliases. The apparatus includes an image pick-up device for viewing the input image and transmitting radiation to the image sensing device, an analog-to-digital converter for converting the analog signal from a sensing device to a digital signal, a position encoder, an interpolator and a memory means for storing the output of the interpolator.
