Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

H04N 9/73

US Classification:

3482231, 348E09051

Abstract:

Methods and systems for face detection and tracking using an image-based capture device are disclosed herein. The method includes generating a depth image of a scene, generating a mask image from the depth image, and detecting a position of a face of a user in the scene using the mask image. The method also includes determining an intensity of the face using a first color channel of the mask image and adjusting a gain level of a first color channel of the image-based capture device directed at the scene to achieve a target intensity of the face.

Abstract:

A three-dimensional shape parameter computation system and method for computing three-dimensional human head shape parameters from two-dimensional facial feature points. A series of images containing a user's face is captured. Embodiments of the system and method deduce the 3D parameters of the user's head by examining a series of captured images of the user over time and in a variety of head poses and facial expressions, and then computing an average. An energy function is constructed over a batch of frames containing 2D face feature points obtained from the captured images, and the energy function is minimized to solve for the head shape parameters valid for the batch of frames. Head pose parameters and facial expression and animation parameters can vary over each captured image in the batch of frames. In some embodiments this minimization is performed using a modified Gauss-Newton minimization technique using a single iteration.

US Classification:

345430

Abstract:

A method and apparatus for generating an illustration having the steps of inputting a plurality of strokes in an area having a designated dimension, assigning a texture and tone to the area, where the tone determines the nature and quantity of the plurality of strokes, generating the texture and the tone assigned in that portion of the illustration, and outputting the illustration.

Abstract:

An online voting system provides a standardized database architecture that integrates editorial and production processes. The voting system has a survey database to store multiple surveys and a server to serve the surveys over a network (e. g. , the Internet) to readers. Each survey consists of one or more questions and multiple answer options per question. The voting system includes an authoring tool to permit an editor to construct the surveys. The surveys are stored in a predefined survey index tables. A display handler checks reader requests for pages that contain surveys, to determine whether the reader should receive a voting form or survey results. A vote handler processes votes cast by the readers in response to the surveys. Unique identifiers of voters who respond to the surveys are collected in a votes table. This table is checked when each vote is received to prevent readers from voting multiple times for a single survey.

US Classification:

345431

Abstract:

A watercolor model based on an ordered set of translucent glazes, which are created independently usinig a shallow water fluid simulation. A Kubelka-Munk compositing model is used for simulating the optical effect of the superimposed glazes. The computer generated watercolor model is used as part of an interactive watercolor paint system, or as a method for automatic image "watercolorization. ".

Abstract:

Systems, methods, and computer-executable instructions for connecting devices includes receiving a device identifier associated with a second device. A search is initiated for a second device profile associated with the device identifier using the device identifier. The second device profile is received. The second device profile includes a device address and a link key. The link key was generated by a second device different from the first device. The address of the first device is set to the device address. Encrypted data is received from the second device addressed to the address.

G06T 11/60

Abstract:

Systems and methods for person counting are disclosed. A method may include retrieving an image frame from a plurality of image frames captured by a camera. The image frame may be split into a grid of a plurality of cells of a pre-determined cell dimensions. The pre-determined cell dimensions may be based on dimensions of the retrieved image frame and reference dimensions of training images of a person detection classifier. At least a portion of the plurality of cells may be rearranged to generate a new image. The new image may be padded with at least one padding strip to adjust dimensions of the new image to the reference dimensions of the training images. Person detection may be performed using the new image and the person detection classifier to obtain a number of persons detected within the new image.

Abstract:

A vehicle camera system captures and transmits video to a user device, which includes a viewing device for playback of the captured video, such as virtual reality or augmented reality glasses. A rendering map is generated that indicates which pixels of the video frame (as identified by particular coordinates of the video frame) correspond to which coordinates of a virtual sphere in which a portion of the video frame is rendered for display. When a video frame is received, the rendering map is used to determine the texture values (e.g., colors) for coordinates in the virtual sphere, which is used to generate the display for the user. This technique reduces the rendering time when a user turns his or her head (e.g., while in virtual reality) and so it reduces motion and/or virtual reality sickness induced by the rendering lag.
