Abstract:
Methods, systems and computer program products (“software”) enable a virtual three-dimensional visual experience (referred to herein as “V 3 D”) in videoconferencing and other applications; the capturing, processing and displaying of images and image streams; and generation of a facial signature based on images of a given human user's or subject's face, or lace and head, for accurate, reliable identification or authentication of a human user or subject, in a secure, difficult to forge manner.

Claim (Index 136):
A video capture system that enables a first user to view a second user with direct virtual eye contact with the second user, the system comprising;\n at least one camera having a view of the second user's face; and a digital processor operable to receive image data from the at least one camera and process the received image data; the system being operable to: capture images of the second user, utilizing the at least one camera; execute, utilizing the processor, a feature correspondence function by detecting common features between corresponding images captured by the at least one camera and measuring a relative distance in image space between the common features, to generate disparity values; generate, utilizing the processor, a data representation, representative of the captured images and the corresponding disparity values; estimate, utilizing the processor, a three-dimensional (3D) location of the first users head, face or eyes, thereby generating tracking information; and reconstruct, utilizing the processor, a synthetic view of the second user, based on the representation, to enable a display to the first user of a synthetic view of the second user in which the second user appears to be gazing directly at the first user, wherein the reconstructing of a synthetic view of the second user comprises reconstructing the synthetic view based on the generated data representation and the generated tracking information; and wherein the location estimating comprises: passing a captured image of the first user, the captured image including the first user's head and face, to a two-dimensional (2D) facial feature detector that utilizes the image to generate a first estimate of head and eye location and a rotation angle of the face relative to an image plane; utilizing an estimated center-of-face position, face rotation angle, and head depth range based on the first estimate, to determine a best-fit rectangle that includes the head; extracting from the best-fit rectangle all 3D points that lie within the best-fit rectangle, and calculating therefrom a representative 3D head position; and if the number of valid 3D points extracted from the best-fit rectangle exceeds a selected threshold in relation to the maximum number of possible 3D points in the region, then signaling a valid 3D head position result.
