    • A system facilitates automatic recognition of facial expressions or other facial attributes. The system includes a data access module and an expression engine. The expression engine further includes a set of specialized expression engines, a pose detection module, and a combiner module. The data access module accesses a facial image of a head. The set of specialized expression engines generates a set of specialized expression metrics, where each specialized expression metric is an indication of a facial expression of the facial image assuming a specific orientation of the head. The pose detection module determines the orientation of the head from the facial image. Based on the determined orientation of the head and the assumed orientations of each of the specialized expression metrics, the combiner module combines the set of specialized expression metrics to determine a facial expression metric for the facial image that is substantially invariant to the head orientation.
    • 系统便于自动识别面部表情或其他面部属性。 该系统包括数据访问模块和表达式引擎。 表达式引擎还包括一组专用表达式引擎,姿态检测模块和组合器模块。 数据访问模块访问头部的面部图像。 专门的表达式引擎集合产生一组特殊的表达度量,其中每个专门的表达度量是表示头部的特定取向的面部图像的面部表情的指示。 姿势检测模块从脸部图像确定头部的方向。 基于所确定的头部方向和每个专门表达度量的假定取向,组合器模块组合了一组专用表情度量以确定面部图像的面部表情度量,该面部图像基本上不变于头部方向。

    • Apparatus, methods, and articles of manufacture for obtaining examples that break a visual expression classifier at user devices such as tablets, smartphones, personal computers, and cameras. The examples are sent from the user devices to a server. The server may use the examples to update the classifier, and then distribute the updated classifier code and/or updated classifier parameters to the user devices. The users of the devices may be incentivized to provide the examples that break the classifier, for example, by monetary reward, access to updated versions of the classifier, public ranking or recognition of the user, a self-rewarding game. The examples may be evaluated using a pipeline of untrained crowdsourcing providers and trained experts. The examples may contain user images and/or depersonalized information extracted from the user images.
    • 用于获得例如在诸如平板电脑,智能电话,个人计算机和照相机之类的用户设备处断开视觉表达分类器的示例的装置,方法和制品。 这些示例从用户设备发送到服务器。 服务器可以使用示例来更新分类器,然后将更新的分类器代码和/或更新的分类器参数分发给用户设备。 可以激励设备的用户提供例如通过金钱奖励,访问分类器的更新版本,公共排名或用户识别,自我奖励游戏来破坏分类器的示例。 这些例子可以使用未经培训的众包提供商和经过培训的专家的管道进行评估。 这些示例可以包含从用户图像提取的用户图像和/或非个人化信息。
