Abstract: Object tracking, such as may involve face tracking, can utilize different detection templates that can be trained using different data. A computing device can determine state information, such as the orientation of the device, an active illumination, or an active camera to select an appropriate template for detecting an object, such as a face, in a captured image. Information about the object, such as the age range or gender of a person, can also be used, if available, to select an appropriate template. In some embodiments instances of templates can be used to process various orientations, while in other embodiments specific orientations, such as upside down orientations, may not be processed for reasons such as rate of inaccuracies or infrequency of use for the corresponding additional resource overhead.
Abstract translation: 对象跟踪，例如可能涉及面部跟踪，可以利用可以使用不同数据进行训练的不同检测模板。 计算设备可以确定状态信息，诸如设备的方向，活动照明或活动照相机，以选择用于检测拍摄图像中的对象（例如脸部）的适当模板。 关于对象的信息，如人的年龄范围或性别，也可以使用（如果有的话）来选择适当的模板。 在一些实施例中，可以使用模板的实例来处理各种取向，而在其他实施例中，由于诸如对于相应的额外资源开销的使用的不准确率或不频率的原因，可能无法处理特定取向，例如上下取向。

Abstract: An aerial vehicle is configured to operate within indoor spaces. The aerial vehicle is programmed with positions of waypoints within three-dimensional space, and to calculate a trajectory for traveling through such waypoints in a manner that minimizes snap of the aerial vehicle. Where a distance between a pair of the waypoints is sufficiently long, the aerial vehicle inserts intervening waypoints for planning purposes, and programs the aerial vehicle to travel at a maximum speed between the intervening waypoints. Upon detecting an obstacle with a first range using one or more sensors, the aerial vehicle reduces its speed and monitors a second, shorter range using the sensors, and compensates for motion between such readings.

Abstract: Various embodiments enable a primary user to be identified and tracked using stereo association and multiple tracking algorithms. For example, a face detection algorithm can be run on each image captured by a respective camera independently. Stereo association can be performed to match faces between cameras. If the faces are matched and a primary user is determined, a face pair is created and used as the first data point in memory for initializing object tracking. Further, features of a user's face can be extracted and the change in position of these features between images can determine what tracking method will be used for that particular frame.

Abstract translation: 各种实施例使得能够使用立体声关联和多个跟踪算法来识别和跟踪主要用户。 例如，可以独立地通过各个相机拍摄的每个图像上运行面部检测算法。 可以执行立体声协会来匹配相机之间的面孔。 如果脸部匹配并且确定了主要用户，则创建面部对并将其用作用于初始化对象跟踪的存储器中的第一数据点。 此外，可以提取用户面部的特征，并且图像之间的这些特征的位置变化可以确定将为该特定帧使用什么跟踪方法。
