摘要： A peer-aware voice stream ranking method that makes decisions based on information about participants of a voice conference over a network. Whether to send a participant's own audio packet out on the network is based both on information about the participant's own voice packet and voice packets that the participant receives from other clients. A Voice Activity Score (VAS) is computed for each frame of a particular voice stream. The VAS includes a voiceness component, indicating the likelihood that the audio frame contains speech or voice, and an energy level component that indicating the ratio of current frame energy to the long-term average of energy for a current speaker. Using the VAS from the participants, the method also ranks the client's voice stream as compared to other clients' voice streams in the voice conference. If there are participants higher ranking, the client's voice stream is not sent.
摘要翻译：基于通过网络进行语音会议的参与者的信息进行决策的对等感知语音流排序方法。是否在网络上发送参与者自己的音频数据包都是基于参与者自己的语音数据包和参与者从其他客户端收到的语音数据包的信息。为特定语音流的每个帧计算语音活动分数（VAS）。 VAS包括声音分量，指示音频帧包含语音或语音的可能性，以及指示当前帧能量与当前说话者的长期能量平均值的比率的能量分量。使用来自参与者的VAS，与语音会议中的其他客户端的语音流相比，该方法还对客户端的语音流进行排序。如果参与者排名较高，则不会发送客户端的语音流。

摘要： An integrated interactive segmentation with spatial constraint method utilizes a combination of several of the most popular online learning algorithms into one and implements a spatial constraint which defines a valid mask local to the user's given marks. Additionally, both supervised learning and statistical analysis are integrated, which are able to compensate each other. Once prediction and activation are obtained, pixel-wised multiplication is conducted to fully indicate how likely each pixel belongs to the foreground or background.
