Abstract: Actions or activities occurring within an environment may be detected, recognized and classified based on the presence or absence of objects within the environment, which may be recognized within imaging data. The states or changes in states of the objects may be tracked within the imaging data and associated with one or more actions or activities with various probabilities. By tracking the motion of objects, rather than the motion of humans or other actors, the detection and classification of actions or activities may be performed more quickly and efficiently, and may be used to determine the timing associated with one or more steps of such activities, as well as whether each of the steps of an activity has been satisfactorily performed and in an appropriate order.

Abstract translation: 环境中发生的动作或活动可以基于环境中存在或不存在可以在成像数据内被识别的物体的存在或不存在来检测，识别和分类。 可以在成像数据内跟踪对象的状态或状态的变化，并且与具有各种概率的一个或多个动作或活动相关联。 通过跟踪对象的运动，而不是人类或其他行动者的动作，可以更快速和有效地执行动作或活动的检测和分类，并且可以用于确定与这种活动的一个或多个步骤相关联的时间 以及活动的每个步骤是否已经令人满意地执行并以适当的顺序进行。
