Abstract: Occupancy in a vehicle is determined by maintaining a set of occupant regions detected in a video. An occupant region can be a bounding box around a face, and/or an occupied seat that does not overlap any bounding box. A count, specific to an occupant region, is set to zero when an overlap between the occupant region in a current frame in the video and a previous frame in the video, satisfies a first predetermined condition. When the overlap does not satisfy the first predetermined condition, the count which is specific to the occupant region is incremented and checked against a threshold in a second predetermined condition. When the count exceeds the threshold, that occupant region is removed from the set of occupant regions. The just-described operations are repeated, with additional occupant regions. A count of occupant regions currently in the set may be displayed or transmitted to a server.

Abstract translation: 通过维持在视频中检测到的一组乘员区域来确定车辆中的乘客。 乘客区域可以是面部周围的边框，和/或不与任何边界框重叠的被占用的座椅。 当视频中的当前帧中的乘员区与视频中的前一帧之间的重叠满足第一预定条件时，对乘客区域特定的计数被设置为零。 当重叠不满足第一预定条件时，相对于第二预定条件的阈值增加和检查对占用区域特有的计数。 当计数超过阈值时，该乘员区域从乘员区域组中移除。 重复了刚才描述的操作，并增加了乘客区域。 目前在集合中的乘员区域的计数可以显示或发送到服务器。

Abstract: Methods, and mobile devices implementing the methods, identify the types of activities performed by a software application operating on a computing device, and take responsive actions based on the detected activity types. For example, the computing device may determine an application type of the software based on metadata associated with the software application, select a lookup table based on the determined application type, determining the types of activities performed by the software application based on the selected lookup table, and select, determine or performing a responsive action based on the types of activities performed by the software application on the computing device.
