摘要： Existing remote workspace sharing systems are difficult to use. For example, changes made on a common work product by one user often appear abruptly on displays viewed by remote users. As a result the interaction is perceived as unnatural by the users and is often inefficient. Images of a display of a common work product are received from a camera at a first location. These images may also comprise information about objects between the display and the camera such as a user's hand editing a document on a tablet PC. These images are combined with images of the shared work product and displayed at remote locations. Advance information about remote user actions is then visible and facilitates collaborative mediation between users. Depth information may be used to influence the process of combining the images.

摘要： There is a need to provide simple, accurate, fast and computationally inexpensive methods of object and hand pose recognition for many applications. For example, to enable a user to make use of his or her hands to drive an application either displayed on a tablet screen or projected onto a table top. There is also a need to be able to discriminate accurately between events when a user's hand or digit touches such a display from events when a user's hand or digit hovers just above that display. A random decision forest is trained to enable recognition of hand poses and objects and optionally also whether those hand poses are touching or not touching a display surface. The random decision forest uses image features such as appearance, shape and optionally stereo image features. In some cases, the training process is cost aware. The resulting recognition system is operable in real-time.

摘要： A method of segmenting image elements into a foreground and background is described, such that only the foreground elements are part of a volume of interest for stereo matching. This reduces computational burden as compared with computing stereo matching over the whole image. An energy function is defined using a probabilistic framework and that energy function approximated to require computation only over foreground disparities. An optimization algorithm is used on the energy function to perform the segmentation.

摘要： Radial distribution of etch rate is controlled by controlling the respective duty cycles of pulsed VHF source power applied to the ceiling and pulsed HF or MF bias power on the workpiece. Net average electrical charging of the workpiece is controlled by providing an electronegative process gas and controlling the voltage of a positive DC pulse on the workpiece applied during pulse off times of the pulsed VHF source power.
