Appl. No.:

12/078464

International Classification:

G06K 9/36

US Classification:

382118

Abstract:

A method and system of identity masking to obscure identities corresponding to face regions in an image is disclosed. A face detector is applied to detect a set of possible face regions in the image. Then an identity masker is used to process the detected face regions by identity masking techniques in order to obscure identities corresponding to the regions. For example, a detected face region can be blurred as if it is in motion by a motion blur algorithm, such that the blurred region can not be recognized as the original identity. Or the detected face region can be replaced by a substitute facial image by a face replacement algorithm to obscure the corresponding identity.

International Classification:

H04B 15/00

US Classification:

381 941, 381150, 381122

Abstract:

A platform that is configured to be removably placed symmetrically on or about a user's head has at least a first transducer configured to capture vibration of the user's skull or facial movement generated by the user's voice activity and to detect the user's speaking activity. This first transducer converts the vibration or facial movement into a first electrical audio signal. The electrical audio signal from the first transducer is processed by circuitry or embodied software as voiced frames and/or as unvoiced frames, in which the voiced frames and/or the unvoiced frames are defined based at least on the first electrical audio signal. Multiple embodiments follow from this: where the first transducer is a vibration sensor; where voice is captured by an air microphone and filtering adaptation differs for the voiced versus unvoiced frames as defined by the first transducer, and another with at least three air microphones.

International Classification:

G06T 1500

US Classification:

395119

Abstract:

Three-dimensional scenes are portrayed from different viewpoints by morphing two-dimensional images. Various key views of a scene are stored, along with offset maps that identify the correspondence of pixels in adjacent stored images. When an intermediate view of the scene is to be presented, one or more stored views are interpolated through a morphing technique. Since the key views and their offset data are pre-stored, the morphing and presentation of new views can be carried out at interactive rates. By providing the ability to quickly compute many closely spaced views, the disclosed morphing technique also facilitates the rapid computation of soft shadows and motion blur in images.

International Classification:

G06T 1300

US Classification:

395173

Abstract:

An animation system employs scattered data interpolation to provide fluent animation of still images. Discontinuities, such as cuts and holes, can be established within an image, to limit the range over which interpolation is carried out for a given deformation of a feature in the image, and thereby refine the control exerted by animated features. The amount of computational time and effort required to interpolate the change from one frame of an animation to the next is reduced by concentrating computation of the deformed image on areas of change. Computational requirements are further reduced by taking advantage of frame-to-frame coherence.

International Classification:

H03M 166

US Classification:

341144

Abstract:

A method and system for reconstructing quantized signals is described. Non-linear filtering is applied to a quantized signal to distribute quantum changes over their respective time intervals to provide, for example, a smoother reconstructed signal. The quantization bounds are enforced for each refined signal point to ensure a reconstructed signal that is within the bounded uncertainty associated with the original signal. The process can be applied to selected control points of the quantized signal and non-overshooting splines can be used to interpolate therebetween.

H04N 5/225
H04N 7/18

Abstract:

A remote-demonstration system for demonstrating products to customers from a remote location. The remote-demonstration system may include a space for demonstrating a variety of products, lighting for illuminating the products and/or the demonstration space, and a device for capturing video of the products that may be sent to customers as part of a live remote product demonstration. The remote-demonstration system may include a product-display tray on which products may be displayed side-by-side or layered one above the other. The remote-demonstration system may provide a consistent, company-branded visual experience to customers viewing the demonstration by, for example, showing the products being demonstrated in a clean, visually-appealing environment.
