摘要： Technologies for generating an avatar with a facial expression corresponding to a facial expression of a user include capturing a reference user image of the user on a computing device when the user is expressing a reference facial expression for registration. The computing device generates reference facial measurement data based on the captured reference user image and compares the reference facial measurement data with facial measurement data of a corresponding reference expression of the avatar to generate facial comparison data. After a user has been registered, the computing device captures a real-time facial expression of the user and generates real-time facial measurement data based on the captured real-time image. The computing device applies the facial comparison data to the real-time facial measurement data to generate modified expression data, which is used to generate an avatar with a facial expression corresponding with the facial expression of the user.
摘要翻译：用于生成具有与用户的面部表情相对应的面部表情的化身的技术包括当用户表达用于注册的参考面部表情时，在计算设备上捕获用户的参考用户图像。计算装置基于捕获的参考用户图像生成参考面部测量数据，并将参考面部测量数据与化身的对应参考表达式的面部测量数据进行比较以生成面部比较数据。在用户注册之后，计算设备捕获用户的实时面部表情，并且基于所捕获的实时图像生成实时面部测量数据。计算装置将面部比较数据应用于实时面部测量数据，以产生修改后的表达数据，该修改的表情数据用于生成具有与用户面部表情相对应的面部表情的化身。

摘要： A cost-effective and computationally efficient hand gesture recognition system for detecting and/or tracking a face region and/or a hand region in a series of images. A skin segmentation model is updated with skin pixel information from the face and iteratively applied to the pixels in the hand region, to more accurately identify the pixels in the hand region given current lighting conditions around the image. Shape features are then extracted from the image, and based on the shape features, a hand gesture is identified in the image. The identified hand gesture may be used to generate a command signal to control the operation of an application or system.

摘要： A thread scheduler may be used in a chip multiprocessor or symmetric multiprocessor system to schedule threads to processors. The scheduler may determine the bandwidth utilization of the two threads in combination and whether that utilization exceeds the threshold value. If so, the threads may be scheduled on different processor clusters that do not have the same paths between the common memory and the processors. If not, then the threads may be allocated on the same processor cluster that shares cache among processors.
摘要翻译：线程调度器可以用在芯片多处理器或对称多处理器系统中以将线程调度到处理器。调度器可以组合确定两个线程的带宽利用率以及该利用率是否超过阈值。如果是这样，线程可能被调度在公共存储器和处理器之间没有相同路径的不同处理器集群上。如果没有，那么线程可能会分配在处理器之间共享高速缓存的同一个处理器集群上。

摘要： The present disclosure describes a method and apparatus for accelerating computation of a Hough transform of a plurality of digital images of known width and height dimensions. The method includes determining a plurality of Hough values for each pixel location based on the width and height dimensions. The method further includes generating a lookup table comprising an array of Hough values corresponding to one or more Hough parameters of at least one geometric shape in at least one digital image. Each element in the array of Hough values may be based on a value of one or more Hough parameters and at least one of a height value or a width value. The method may include receiving a plurality of digital images having known width and height dimensions. The method may further include selecting, for at least one nonzero pixel of at least one of the plurality of digital images, the Hough values from the lookup table. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.
