摘要： Techniques are provided for establishing a videoconference session between participants at different endpoints, where each endpoint includes at least one computing device and one or more displays. A plurality of video streams is received at an endpoint, and each video stream is classified as at least one of a people view and a data view. The classified views are analyzed to determine one or more regions of interest for each of the classified views, where at least one region of interest has a size smaller than a size of the classified view. Synthesized views of at least some of the video streams are generated, wherein the synthesized views include at least one view including a region of interest, and views including the synthesized views are rendered at one or more displays of an endpoint device.

摘要： A system and method for alerting participants in a videoconference that one or more participants are improperly framed by the videoconference camera is provided. An embodiment comprises a temporary self-view picture-in-picture image appearing when the number of faces detected by the videoconference camera changes. A face detection algorithm is used to determine when the number of faces being detected by the videoconference camera has changed. The self-view picture-in-picture image displays, for a duration of time, a representation of the image being captured by the videoconference camera, allowing participants who are not properly framed by the videoconference camera to adjust their position to that their faces are captured by the videoconference camera.

摘要： A method is provided in one example and includes receiving image data for a field of view associated with a display. The image data is used to generate a plurality of red green blue (RGB) frames. The method also includes emitting infrared energy onto the field of view in order to generate a plurality of infrared frames, the plurality of RGB frames and the plurality of infrared frames are generated by a single camera. The plurality of RGB frames can be combined with the plurality of infrared frames in order to generate a video data stream. In a more particular embodiment, the emitting of the infrared energy is synchronized with the camera such that the infrared energy is emitted onto the field of view at one half of an existing frame rate of the camera.

摘要： An apparatus, a method, and a computer-readable medium having instructions encoded thereon that when executed cause a method to be carried out. The method includes dividing at least a portion of a picture of a video stream into parts of blocks, and processing the parts in parallel by a plurality of interconnected processors. The processing of a respective part by its respective processor includes determining block-level temporal difference features. Each processor also performs coding functions on its respective part of the picture. The method also includes block-level processing using the block-level temporal difference features to determine which blocks in the picture are likely to be that of a face, the block-level processing being at the granularity of at least a block. In one version, the processing in each processor includes edge detection and color segmentation to determine block-level edge features including block-level color-segmented edge features that are then used in the block level processing.

摘要： A method that includes capturing depth information associated with a first field of view of a depth camera. The depth information is represented by a first plurality of depth pixels. The method also includes capturing color information associated with a second field of view of a video camera that substantially overlaps with the first field of view of the depth camera. The color information is represented by a second plurality of color pixels. The method further includes enhancing color information represented by at least one color pixel of the second plurality of color pixels to generate an enhanced image. The enhanced image adjusts an exposure characteristic of the color information captured by the video camera. The at least one color pixel is enhanced based on depth information represented by at least one corresponding depth pixel of the first plurality of depth pixels.
