    摘要: In an embodiment, a method of creating a skimming preview of a video includes electronically receiving a plurality of video shots, analyzing each frame in a video shot from the plurality of video shots, where analyzing includes determining a saliency of each frame of the video shot. The method also includes determining a key frame of the video shot based on the saliency of each frame the video shot, extracting visual features from the key frame, performing shot clustering of the plurality of video shots to determine concept patterns based on the visual features, and generating a reconstruction reference tree based on the shot clustering. The reconstruction reference tree includes video shots categorized according to each concept pattern.

    摘要: A system and method for retargeting video sequences are provided. A method for retargeting a video includes a plurality of frames includes determining saliency information for the plurality of frames, determining a cost metric for the video, and retargeting the video based on the cost metric to produce a retargeted video. The cost metric considers loss due to cropping, scaling, temporal factors, and spatial factors. The retargeting makes use of a crop window for each frame in the plurality of frames.

    摘要: In one embodiment, a device is connected to a first computer via a first local communication port of the first computer. If the device is configured to autoconnect with a second computer upon connection of the device to the first computer, a remote access session is established between the first computer and the second computer. Low-level local communication from the device is intercepted at the first local communication port of the first computer. The low-level local communication is transmitted from the first computer to the second computer via the remote access session. The low-level local communication is injected to a second local communication port of the second computer to thereby provide an autoconnection of the device to the second computer.

    摘要: In one embodiment, a client device may send one or more sub-session requests to one or more corresponding session controllers through a computer network to obtain one or more corresponding sub-session tokens that indicate in which sub-sessions of an online collaborative computing session the client device is permitted to participate. The client device may then receive particular sub-session tokens (e.g., based on certain permissions), which may then be sent to a collaboration server to establish one or more permitted sub-sessions of the online collaborative computing session with the client device as indicated by the received sub-session tokens.
