Abstract: 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.

Abstract: A system and method are disclosed for recognizing and tracking a user's skeletal joints with a NUI system and further, for recognizing and tracking only some skeletal joints, such as for example a user's upper body. The system may include a limb identification engine which may use various methods to evaluate, identify and track positions of body parts of one or more users in a scene. In examples, further processing efficiency may be achieved by segmenting the field of view in smaller zones, and focusing on one zone at a time. Moreover, each zone may have its own set of predefined gestures which are recognized.

Abstract: Systems and methods are disclosed for identifying objects captured by a depth camera by condensing classified image data into centroids of probability that captured objects are correctly identified entities. Output exemplars are processed to detect spatially localized clusters of non-zero probability pixels. For each cluster, a centroid is generated, generally resulting in multiple centroids for each differentiated object. Each centroid may be assigned a confidence value, indicating the likelihood that it corresponds to a true object, based on the size and shape of the cluster, as well as the probabilities of its constituent pixels.

Abstract: A method of tracking a target includes receiving from a source an observed depth image of a scene including the target. Each pixel of the observed depth image is labeled as either a foreground pixel belonging to the target or a background pixel not belonging to the target. Each foreground pixel is labeled with body part information indicating a likelihood that that foreground pixel belongs to one or more body parts of the target. The target is modeled with a skeleton including a plurality of skeletal points, each skeletal point including a three dimensional position derived from body part information of one or more foreground pixels.
