摘要： Embodiments include methods and systems which determine pixel displacement between frames based on a respective weighting-value for each pixel or a group of pixels. The weighting-values provide an indication as to which pixels are more pertinent to optical flow computations. Computational resources and effort can be focused on pixels with higher weights, which are generally more pertinent to optical flow determinations.

摘要： In general, this disclosure describes techniques for providing a gesture-based user interface. For example, according to some aspects of the disclosure, a user interface generally includes a camera and a computing device that identifies and tracks the motion of one or more fingertips of a user. In some examples, the user interface is configured to identify predefined gestures (e.g., patterns of motion) associated with certain motions of the user's fingertips. In another example, the user interface is configured to identify hand postures (e.g., patterns of showing up of fingertips). Accordingly, the user can interact with the computing device by performing the gestures.

摘要： A mobile device has a housing having first and second display areas. A mic-array is integrated into the housing and has microphones operable to sense sound signals at multiple locations on the housing from a sound pen when handwriting an alphanumeric symbol on a surface separate from and in proximity to the housing. A handwriting-to-text converter is operable to graphically represent, for display on the first display area, simulated handwritten traces of the alphanumeric symbol and to convert the alphanumeric symbol into a computer-readable interchange code, representative of the alphanumeric symbol, for display in the second display area.

摘要： This disclosure describes an apparatus, such as a wireless communication device, that applies a direct evaluation technique to render triangles for the 3D graphical environment. The apparatus includes a rendering engine that defines a rectangular area of pixels, referred to as a bounding box, that bounds the area to be rendered. The rendering engine evaluates coordinates associated with the pixels of the rectangular area to selectively render those pixels that fall within the triangular area. The direct evaluation triangle rendering algorithm may require fewer complex operations than the more computationally intensive interpolation process employed by other systems. As a result, the apparatus may present a 3D graphical environment while preserving as much as possible the available power.

摘要翻译：本公开描述了一种诸如无线通信设备的装置，其应用直接评估技术来渲染3D图形环境的三角形。该装置包括描绘引擎，该引擎定义了限定要渲染的区域的被称为边界框的像素的矩形区域。渲染引擎评估与矩形区域的像素相关联的坐标，以选择性地渲染落在三角形区域内的像素。直接评估三角形渲染算法可能需要比其他系统使用的计算密集型插值过程更少的复杂操作。结果，该装置可以呈现3D图形环境，同时尽可能多地保留可用功率。

摘要： A histogram modeling based technique for image contrast enhancement. In some implementations, a histogram of an image is created and then transformed. Using the physics of sound or heat propagation, the technique may develop a spreaded histogram model that may be transformed. A nonlinear mapping may be created to remap an image for contrast enhancement. The technique may be performed without threshold tuning and may be implemented on a variety of display hardware.

摘要： In a particular illustrative embodiment, a method of determining a viewpoint of a person based on skin color area and face area is disclosed. The method includes receiving image data corresponding to an image captured by a camera, the image including at least one object to be displayed at a device coupled to the camera. The method further includes determining a viewpoint of the person relative to a display of the device coupled to the camera. The viewpoint of the person may be determined by determining a face area of the person based on a determined skin color area of the person and tracking a face location of the person based on the face area. One or more objects displayed at the display may be moved in response to the determined viewpoint of the person.

摘要： A three dimensional (3D) mixed reality system combines a real 3D image or video, captured by a 3D camera for example, with a virtual 3D image rendered by a computer or other machine to render a 3D mixed-reality image or video. A 3D camera can acquire two separate images (a left and a right) of a common scene, and superimpose the two separate images to create a real image with a 3D depth effect. The 3D mixed-reality system can determine a distance to a zero disparity plane for the real 3D image, determine one or more parameters for a projection matrix based on the distance to the zero disparity plane, render a virtual 3D object based on the projection matrix, combine the real image and the virtual 3D object to generate a mixed-reality 3D image.
