摘要： A novel enhanced beamforming technique that improves beamforming operations by incorporating a model for the directional gains of the sensors, such as microphones, and provides means of estimating these gains. The technique forms estimates of the relative magnitude responses of the sensors (e.g., microphones) based on the data received at the array and includes those in the beamforming computations.

摘要： A multi-sensor sound source localization (SSL) technique is presented which provides a true maximum likelihood (ML) treatment for microphone arrays having more than one pair of audio sensors. Generally, this is accomplished by selecting a sound source location that results in a time of propagation from the sound source to the audio sensors of the array, which maximizes a likelihood of simultaneously producing audio sensor output signals inputted from all the sensors in the array. The likelihood includes a unique term that estimates an unknown audio sensor response to the source signal for each of the sensors in the array.

摘要： Multi-view video that is being streamed to a remote device in real time may be encoded. Frames of a real-world scene captured by respective video cameras are received for compression. A virtual viewpoint, positioned relative to the video cameras, is used to determine expected contributions of individual portions of the frames to a synthesized image of the scene from the viewpoint position using the frames. For each frame, compression rates for individual blocks of a frame are computed based on the determined contributions of the individual portions of the frame. The frames are compressed by compressing the blocks of the frames according to their respective determined compression rates. The frames are transmitted in compressed form via a network to a remote device, which is configured to render the scene using the compressed frames.

摘要： A “speech onset detector” provides a variable length frame buffer in combination with either variable transmission rate or temporal speech compression for buffered signal frames. The variable length buffer buffers frames that are not clearly identified as either speech or non-speech frames during an initial analysis. Buffering of signal frames continues until a current frame is identified as either speech or non-speech. If the current frame is identified as non-speech, buffered frames are encoded as non-speech frames. However, if the current frame is identified as a speech frame, buffered frames are searched for the actual onset point of the speech. Once that onset point is identified, the signal is either transmitted in a burst, or a time-scale modification of the buffered signal is applied for compressing buffered frames beginning with the frame in which onset point is detected. The compressed frames are then encoded as one or more speech frames.
摘要翻译： “语音起始检测器”提供了可变长度帧缓冲器，与缓冲信号帧的可变传输速率或时间语音压缩相结合。可变长度缓冲器缓冲在初始分析期间未被清楚地识别为语音或非语音帧的帧。信号帧的缓冲持续到当前帧被识别为语音或非语音。如果当前帧被识别为非语音，则缓冲帧被编码为非语音帧。然而，如果当前帧被识别为语音帧，则搜索缓冲的帧用于语音的实际起始点。一旦该起始点被识别，则信号以突发方式发送，或者缓冲信号的时间尺度修改被应用于从检测到起始点的帧开始的缓冲帧。然后将压缩的帧编码为一个或多个语音帧。

摘要： A system and process for finding the location of a sound source using direct approaches having weighting factors that mitigate the effect of both correlated and reverberation noise is presented. When more than two microphones are used, the traditional time-delay-of-arrival (TDOA) based sound source localization (SSL) approach involves two steps. The first step computes TDOA for each microphone pair, and the second step combines these estimates. This two-step process discards relevant information in the first step, thus degrading the SSL accuracy and robustness. In the present invention, direct, one-step, approaches are employed. Namely, a one-step TDOA SSL approach and a steered beam (SB) SSL approach are employed. Each of these approaches provides an accuracy and robustness not available with the traditional two-step approaches.
摘要翻译：提出了使用具有减轻相关和混响噪声的影响的加权因子的直接方法来发现声源的位置的系统和过程。当使用两个以上的麦克风时，传统的基于时间延迟（TDOA）的声源定位（SSL）方法涉及两个步骤。第一步计算每个麦克风对的TDOA，第二步合并这些估计。这两步过程在第一步中丢弃相关信息，从而降低了SSL的准确性和鲁棒性。在本发明中，采用直接的一步法。也就是说，采用一步式TDOA SSL方法和转向束（SB）SSL方法。这些方法中的每一种提供了传统的两步方法不可用的精度和鲁棒性。

摘要： A phishing detection server component and method is provided. The component can be employed as part of a system to detect/phishing attacks. The phishing detection server component can receive password reuse event report(s), for example, from a protection component of client component(s). Due to the malicious nature of phishing in general, the phishing detection server component can be susceptible to attacks by phishers (e.g., by reverse engineering of the client component). For example, false report(s) of PREs can be received from phisher(s) in an attempt to overwhelm the server component, induce false positives and/or induce false negatives. Upon receipt of a PRE report, the phishing detection server component can first verify that the timestamp(s) are genuine (e.g., previously generated by the phishing detection server component). The report verification component can employ the timestamp(s) to verify veracity of the report (e.g., to minimize attacks by phishers).
