摘要： A multimodal system that employs a plurality of sensing modalities which can be processed concurrently to increase confidence in connection with authentication. The multimodal system and/or set of various devices can provide several points of information entry in connection with authentication. Authentication can be improved, for example, by combining face recognition, biometrics, speech recognition, handwriting recognition, gait recognition, retina scan, thumb/hand prints, or subsets thereof. Additionally, portable multimodal devices (e.g., a smartphone) can be used as credit cards, and authentication in connection with such use can mitigate unauthorized transactions.

摘要： Described herein is a technique for creating a 3D face model using images obtained from an inexpensive camera associated with a general-purpose computer. Two still images of the user are captured, and two video sequences. The user is asked to identify five facial features, which are used to calculate a mask and to perform fitting operations. Based on a comparison of the still images, deformation vectors are applied to a neutral face model to create the 3D model. The video sequences are used to create a texture map. The process of creating the texture map references the previously obtained 3D model to determine poses of the sequential video images.

摘要： A method and apparatus determine a channel response for an alternative sensor using an alternative sensor signal, an air conduction microphone signal. The channel response and a prior probability distribution for clean speech values are then used to estimate a clean speech value.

摘要： Calibration for a camera is achieved by receiving images of a calibration object whose geometry is one-dimension in space. The received images show the calibration object in several distinct positions. Calibration for the camera is then calculated based on the received images of the calibration object.
