    • A system and method are disclosed for recognizing and tracking a user's skeletal joints with a NUI system. The system includes one or more experts for proposing one or more skeletal hypotheses each representing a user pose within a given frame. Each expert is generally computationally inexpensive. The system further includes an arbiter for resolving the skeletal hypotheses from the experts into a best state estimate for a given frame. The arbiter may score the various skeletal hypotheses based on different methodologies. The one or more skeletal hypotheses resulting in the highest score may be returned as the state estimate for a given frame. It may happen that the experts and arbiter are unable to resolve a single state estimate with a high degree of confidence for a given frame. It is a further goal of the present system to capture any such uncertainty as a factor in how a state estimate is to be used.
    • 公开了一种用于识别和跟踪用户与NUI系统的骨骼关节的系统和方法。 该系统包括一个或多个专家,用于提出一个或多个骨骼假设,每个骨骼假设表示给定帧内的用户姿态。 每个专家通常在计算上是廉价的。 该系统还包括仲裁器,用于将来自专家的骨骼假设解析成给定帧的最佳状态估计。 仲裁者可以根据不同的方法对各种骨骼假设进行评分。 导致最高分数的一个或多个骨骼假设可以作为给定帧的状态估计返回。 可能发生专家和仲裁者无法以特定框架的高度置信度来解决单一状态估计。 本系统的另一个目标是捕获任何这样的不确定性,因为如何使用状态估计。
