More Information
Summary:Techniques are disclosed for processing a video stream to reduce platform power by employing a stepped and distributed pipeline process, wherein CPU-intensive processing is selectively performed. Thetechniques are particularly well-suited for hand-based navigational gesture processing. In one example case, for instance, the techniques are implemented in a computer system wherein initial thresholddetection (image disturbance) and optionally user presence (hand image) processing components are proximate to or within the system's camera, and the camera is located in or proximate to the system'sprimary display. In some cases, image processing and communication of pixel information between various processing stages which lies outside a marked region is suppressed. In some embodiments, the marked region is aligned with, a mouse pad or designated desk area or a user input device such as a keyboard. Pixels evaluated by the system can be limited to a subset of the marked region. 公开了用于通过采用阶梯状的及分布式管线步骤而对视频流进行处理以降低平台功率的技
