摘要： The example techniques of this disclosure are directed to generating a stereoscopic view from an application designed to generate a mono view. For example, the techniques may modify source code of a vertex shader to cause the modified vertex shader, when executed, to generate graphics content for the images of the stereoscopic view. As another example, the techniques may modify a command that defines a viewport for the mono view to commands that define the viewports for the images of the stereoscopic view.

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： 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.

摘要： This disclosure describes a multi-stage tessellation technique for tessellating a curve during graphics rendering. In particular, a first tessellation stage tessellates the curve into a first set of line segments that each represents a portion of the curve. A second tessellation stage further tessellates the portion of the curve represented by each of the line segments of the first set into additional line segments that more finely represent the shape of the curve. In this manner, each portion of the curve that was represented by only one line segment after the first tessellation stage is represented by more than one line segment after the second tessellation stage. In some instances, more than two tessellation stages may be performed to tessellate the curve.

摘要： A method and apparatus providing a user interface within a phone that responds to a limited vocabulary of user trained voice commands. The interface allows users to perform all phone handset dialing functions using voice commands. Additionally, users will be able to create and modify entries within a voice recognition phonebook, whereby a number within the voice recognition phonebook can be called by saying the name associated with the number. The user interface provides a combination of voice and LCD displayed user prompts and responses to voice input. The interface responds to user voice commands and performs the command functions based upon matches to previously user trained voice command vocabulary words stored in memory.

摘要： The speech recognition training unit is modified to store digitized speech samples into a speech database that can be accessed at recognition time. The improved recognition unit comprises a noise analysis, modeling, and synthesis unit which continually analyzes the noise characteristics present in the audio environment and produces an estimated noise signal with similar characteristics. The recognition unit then constructs a noise-compensated template database by adding the estimated noise signal to each of the speech samples in the speech database and performing parameter determination on the resulting sums. This procedure accounts for the presence of noise in the recognition phase by retraining all the templates using an estimated noise signal with similar characteristics as the actual noise signal that corrupted the word to be recognized. This method improves the likelihood of a good template match, which increases the recognition accuracy.

摘要： A system and method for forming a segmented speech signal from an input speech signal having a plurality of frames. The input speech signal is converted from a time domain signal to a frequency domain signal having a plurality of speech frames, wherein each speech frame in the frequency domain signal is represented by at least one spectral value associated with the speech frame. A spectral difference value is then determined for each pair of adjacent frames in the frequency domain signal, wherein the spectral difference value for each pair of adjacent frames is representative of a difference between the at least one spectral value associated with each frame in the pair of adjacent frames. An initial cluster boundary is set between each pair of adjacent frames in the frequency domain signal, and a variance value is assigned to each cluster in the frequency domain signal, wherein the variance value for each cluster is equal to one of the determined spectral difference values. Next, a plurality of cluster merge parameters is calculated, wherein each of the cluster merge parameters is associated with a pair of adjacent clusters in the frequency domain signal. A minimum cluster merge parameter is selected from the plurality of cluster merge parameters. A merged cluster is then formed by canceling a cluster boundary between the clusters associated with the minimum merge parameter and assigning a merged variance value to the merged cluster, wherein the merged variance value is representative of the variance values assigned to the clusters associated with the minimum merge parameter. The process is repeated in order to form a plurality of merged clusters, and the segmented speech signal is formed in accordance with the plurality of merged clusters.
摘要翻译：一种用于从具有多个帧的输入语音信号形成分段语音信号的系统和方法。输入语音信号从时域信号转换为具有多个语音帧的频域信号，其中频域信号中的每个语音帧由与语音帧相关联的至少一个频谱值表示。然后对频域信号中的每对相邻帧确定频谱差值，其中每对相邻帧的频谱差值表示与该对相邻帧中的每个帧相关联的至少一个频谱值之间的差异相邻帧。在频域信号中的每对相邻帧之间设置初始簇边界，并且将频域值分配给频域信号中的每个簇，其中每个簇的方差值等于所确定的光谱差值之一。接下来，计算多个集群合并参数，其中每个集群合并参数与频域信号中的一对相邻集群相关联。从多个集群合并参数中选择最小集群合并参数。然后通过消除与最小合并参数相关联的集群之间的集群边界并将合并的方差值分配给合并的集群来形成合并的集群，其中合并的方差值表示分配给与最小合并参数相关联的集群的方差值合并参数。重复该过程以形成多个合并的群集，并且根据多个合并的群集形成分段语音信号。
