摘要： An image such as a depth image of a scene may be received, observed, or captured by a device. A grid of voxels may then be generated based on the depth image such that the depth image may be downsampled. A background included in the grid of voxels may also be removed to isolate one or more voxels associated with a foreground object such as a human target. A location or position of one or more extremities of the isolated human target may then be determined.

摘要： A tracking system having a depth camera tracks a user's body in a physical space and derives a model of the body, including an initial estimate of a hand position. Temporal smoothing is performed when the initial estimate moves by less than a threshold level from frame to frame, while little or no smoothing is performed when the movement is more than the threshold. The smoothed estimate is used to define a local volume for searching for a hand extremity to define a new hand position. Another process generates stabilized upper body points that can be used as reliable reference positions, such as by detecting and accounting for occlusions. The upper body points and a prior estimated hand position are used to define an arm vector. A search is made along the vector to detect a hand extremity to define a new hand position.
摘要翻译：具有深度摄像机的跟踪系统在物理空间中跟踪用户的身体并且导出身体的模型，包括手位置的初始估计。当初始估计从帧到帧移动小于阈值水平时执行时间平滑，而当运动大于阈值时执行很少或不进行平滑化。平滑的估计用于定义用于搜索手末端以定义新的手位置的本地体积。另一个过程产生可以用作可靠参考位置的稳定的上身点，例如通过检测和计算遮挡。上身点和先前估计的手位置用于定义手臂矢量。沿向量搜索以检测手末端以定义新的手位置。

摘要： A method of tracking a target includes receiving an observed depth image of the target from a source and analyzing the observed depth image with a prior-trained collection of known poses to find an exemplar pose that represents an observed pose of the target. The method further includes rasterizing a model of the target into a synthesized depth image having a rasterized pose and adjusting the rasterized pose of the model into a model-fitting pose based, at least in part, on differences between the observed depth image and the synthesized depth image. Either the exemplar pose or the model-fitting pose is then selected to represent the target.

摘要： A simultaneous operation flash memory capable of providing double protection to An OTP sector. The preferred simultaneous operation flash memory comprises an OTP write-protect CAM, which is in a programmed state if the OTP sector is write-protected. In addition, the preferred simultaneous flash memory further includes an OTP sector lock CAM that is electrically connected with the OTP write-protect CAM. The OTP sector lock CAM is used to lock the OTP write-protect CAM in the programmed state, which, in turn, will designate the OTP sector as read only.

摘要： Described is a stereoscopic display (telepresence) system that includes a depth cue adjustment mechanism for changing screen disparity to move a fixation distance of a viewer (subject) closer to a focus distance, thereby providing more desirable viewing conditions. In one aspect, the depth cue adjustment mechanism adjusts a depth cue by moving the fixation distance forward, and/or by moving the focus distance backward. Also described is detecting encroachment, where the object is perceived as being too close to the subject viewer for comfort, and adjusting one or more depth cues (e.g., object scale) to counteract the sensation of the encroachment.
摘要翻译：描述了一种立体显示（远程呈现）系统，其包括用于改变画面差异的深度提示调整机构，以使观看者（被摄体）的定位距离更接近焦距，从而提供更理想的观看条件。一方面，深度提示调节机构通过向前移动固定距离和/或通过向后移动聚焦距离来调节深度提示。还描述了检测侵占，其中物体被感知为太靠近被摄体以便舒适，并且调整一个或多个深度线索（例如，对象尺度）以抵消侵占的感觉。
