Abstract: In some embodiments, a computer-implemented method includes capturing an image for each flash unit of an electronic device, each image being illuminated during the capturing of the image; obtaining a normalized image from one or more of the illuminated images; and using an illumination-based optimization framework to generate an enhanced three-dimensional (3D) depth image, the illumination-based optimization framework being based on the illuminated image. In some embodiments of the computer-implemented method, the illumination-based optimization framework incorporates the normalized image and 3D depth data associated with the captured image into the generation of the enhanced 3D depth image.

Abstract: The invention aligns a digital face model from a 3D face scanner with a 3D jaw scan from an intraoral scan produced by an intraoral scanner without using external markers. The alignment proceeds in two steps. In the first step, the teeth part of a subject whose teeth are clenched, referred to as a clenched-teeth face scan, is aligned with an intraoral jaw scan to obtain a first transformation matrix. In the second step, a face model of a subject with a normal facial expression is aligned with the clenched-teeth face model of the same subject to obtain a second transformation matrix. A graphical user interface is provided that enables a user to manually align the 3D jaw scan with a 2D image of the subject's teeth to determine the first transformation.

Abstract: Systems and methods are provided for to estimate the pose of a human subject's head from a sequence of images received from a single depth camera by processing the images to generate a continuous estimate of the head pose in a 3-dimensional (3D) space, and to generate a 3D head model for display and further use. The subject is provided instructions to rotate their head in a first direction until a threshold angle of rotation is reached and then are provided instructions to rotate their head in a second direction. The depth camera provides a sequence of captured images which are processed to extract head meshes. After capture is complete the head meshes are merged to generate a 3D model of the subject's head.

Abstract: According to an embodiment, access to an online resource is enabled by associating a telephony number with a network resource that is made available at a network location, where network resource is protected so as to be inaccessible without access being provided for users individually. A particular user may be detected in initiating a telephony session using the number. Access to the network resource may be activated or authorized for the particular user in response to detecting the user initiating the telephony session.

Abstract: Data may be made available to one or more participants of an online collaboration session through use of a client system that generates or otherwise captures the data to be shared, and then formats that data for use by general-purpose server resources. In one embodiment, data from the operation of an application on the client system is captured. A formatted data set that is suitable for the client-server communications is prepared from the captured data. The formatted data set may be configured with characteristics to enable the server to respond to requests from one or more participant terminals of the online collaboration session. During the session, the formatted data set may be transmitted to the server in one or more discrete and independent communications.

Abstract: An apparatus and method for creating an animation. A sequence of video images is inspected to identify a first transformation of a scene depicted in the sequence of video images. A first image and a second image are obtained from the sequence of video images, the first image representing the scene before the first transformation and the second image representing the scene after the first transformation. Information is generated that indicates the first transformation and that can be used to interpolate between the first image and the second image to produce a video effect that approximates display of the sequence of video images.

Information that indicates an image in an animation that has been created from a second video is stored in one or more of the elements of the data structure.

Abstract: A graphical user interface (“GUI”) is described comprising: a video region for displaying a video of a presenter giving a presentation; a primary slide region for displaying slides used by the presenter during the presentation; and a thumbnail region containing thumbnails representing slides in the presentation, the thumbnails selectable by a user via a cursor control device.
