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.

An educational and training system allows organization and management of computers and course material used in teaching and administering classes of computer based information. Remote users access computers in laboratories or virtual classrooms as if they were actually using the computers within the laboratory or classroom. The system also allows management and tracking of the remote users and of other various course details.

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.

A method and apparatus for forming solar cells is provided. In one embodiment, a photovoltaic device includes a first p-i-n junction cell formed on a substrate, wherein the p-i-n junction cell comprises a p-type silicon containing layer, an intrinsic type silicon containing layer formed over the p-type silicon containing layer, and a n-type silicon containing layer formed over the intrinsic type silicon containing layer, wherein the intrinsic type silicon containing layer comprises a first pair of microcrystalline layer and amorphous silicon layer.
摘要:
A method for forming a semiconductor structure includes forming a plurality of features across a surface of a substrate, with at least one space being between two adjacent features. A first dielectric layer is formed on the features and within the at least one space. A portion of the first dielectric layer interacts with a reactant derived from a first precursor and a second precursor to form a first solid product. The first solid product is decomposed to substantially remove the portion of the first dielectric layer. A second dielectric layer is formed to substantially fill the at least one space.
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.
