A pointing vector is determined for a gesture that is performed before a depth camera. One example includes receiving a first and a second image of a pointing gesture in a depth camera, the depth camera having a first and a second image sensor, applying erosion and dilation to the first image using a 2D convolution filter to isolate the gesture from other objects, finding the imaged gesture in the filtered first image of the camera, finding a pointing tip of the imaged gesture, determining a position of the pointing tip of the imaged gesture using the second image, and determining a pointing vector using the determined position of the pointing tip.

Determining a pointing vector for gestures performed before a depth camera

Systems, apparatuses, and/or methods to characterize a user feature. For example, and apparatus may include a pattern receiver to receive a feature infrared (IR) pattern corresponding to non-uniform IR radiation reflected by skin of the user feature and an object IR pattern corresponding to IR radiation reflected by an object. The apparatus may further include a filter to generate a modified IR pattern from the object IR pattern and to remove at least a part of the modified IR pattern from feature IR pattern. In addition, the apparatus may include a feature characterizer to characterize the user feature based on the feature IR pattern. In one example, a computing platform may be controlled based on the characterization of the user feature.

A video stream may include portions that are stored while other portions are being displayed. In one embodiment, a portion of the video stream may be stored in digital storage media at one instance while in the next instance another portion of the stream is being read out of the storage media.

Time shifting by concurrently recording and playing a data stream

A method for performance monitoring in a computing system is described. In some embodiments, an addressable memory stores data and instructions for performing context switch sampling. A processor includes hardware event counters, and is coupled with the addressable memory to access said instructions and in response to said instructions, the processor counts occurrences of a first hardware event in a first hardware event counter and counts occurrences of a second hardware event in a second hardware event counter. After a specified number of occurrences of the first hardware event have been counted, the second hardware event counter is sampled and hardware event counters are reset. In some embodiments the processor counts occurrences of segment register load events in the first hardware event counter and then records the sampled second hardware event counter value with a process identifier value and/or a thread identifier value.

In some embodiments, the invention includes a method of editing a video stream. The method includes storing segment frame icons representing segments of the video stream, the segment frame icons having a layout. The method further includes displaying at least some of the segment frame icons and responding to signals from a user input device by changing the layout of the segment frame icons. In some embodiments, the segment frame icons are arranged in a two-dimensional grid. The segment frame icons may include an image derived from a representative frames of the segments. Changing the layout may involve one or more of the following: re-arranging an order of the segment frame icons in the layout, deleting at least one of the segment frame icons, and adding at least one segment frame icon from another video stream. The segment frame icons may be shot frame icons representing shots of the video stream. The segment frame icons may be subshot frame icons representing subshots of shots of the video stream. Other embodiments are described and claimed.

In accordance with one embodiment, the invention provides a method comprising monitoring a power consumption of a processor in executing a program while running in a speculative execution mode wherein instructions are speculatively executed; and turning off said speculative execution mode if said power consumption is above a predetermined threshold. According to another embodiment the invention provides a processor comprising a speculative mode wherein instructions are speculatively executed; a non-speculative execution mode wherein instructions are executed non-speculatively; and a speculation control mechanism to selectively cause said processor to operate in said non-speculative mode based on a power consumption criterion.

Method and apparatus for controlling execution of speculations in a processor based on monitoring power consumption

A method for synchronizing the audio track to the video track in a multimedia presentation. Any difference in the frequencies of the clocks of the audio and video drivers are first determined. If the video driver operates according to a faster frequency than the audio driver, audio samples are clipped from the audio track. If the video driver operates according to a slower frequency than the audio driver, audio samples are added to the audio track.
