    • Targeted sound detection methods and apparatus are disclosed. A microphone array has two or more microphones M0 . . . MM. Each microphone is coupled to a plurality of filters. The filters are configured to filter input signals corresponding to sounds detected by the microphones thereby generating a filtered output. One or more sets of filter parameters for the plurality of filters are pre-calibrated to determine one or more corresponding pre-calibrated listening zones. Each set of filter parameters is selected to detect portions of the input signals corresponding to sounds originating within a given listening zone and filter out sounds originating outside the given listening zone. A particular pre-calibrated listening zone is selected at a runtime by applying to the plurality of filters a set of filter coefficients corresponding to the particular pre-calibrated listening zone. As a result, the microphone array may detect sounds originating within the particular listening sector and filter out sounds originating outside the particular listening zone.
    • 公开了目标声音检测方法和装置。 麦克风阵列具有两个或更多个麦克风M 0 0。 。 。 M< M>。 每个麦克风耦合到多个滤波器。 滤波器被配置为对与由麦克风检测到的声音相对应的输入信号进行滤波,从而产生滤波输出。 用于多个滤波器的一组或多组滤波器参数被预校准以确定一个或多个对应的预校准收听区域。 选择每组滤波器参数以检测对应于在给定监听区域内产生的声音的输入信号的部分,并且滤除源自给定监听区域之外的声音。 通过向多个滤波器应用与特定预校准收听区对应的一组滤波器系数,在运行时选择特定的预校准收听区。 结果,麦克风阵列可以检测起源于特定聆听扇区内的声音,并且滤除在特定聆听区域外发出的声音。

    • Computer implemented methods for interactively modifying a video image are provided. The video image can be transmitted between a first user and a second user using a computer program that is executed on at least one computer in a computer network. Additionally, the first user and the second user interact through respective computing systems that at least partially execute the computer program. A video capture system is provided that is interfaced with the computer program that can be used to capture real-time video of the first user. The method continues by identifying components of the video image of the first user that can be modified using real-time effects in the captured real-time video. In another operation, the method identifies controller input from either the first user or the second user. The controller input detected by the computing system is identified to determine which of the identified components of the first user will be modified. In response to the identified controller input, another operation of the method augments the real-time video captured of the first user by applying the real-time effects to the identified components of the first user. The method then displays the augmented real-time video of the first user on a screen connected to the computing system of one or both of the first and second users.
    • 提供了用于交互式修改视频图像的计算机实现方法。 可以使用在计算机网络中的至少一台计算机上执行的计算机程序在第一用户和第二用户之间传输视频图像。 另外,第一用户和第二用户通过至少部分地执行计算机程序的各个计算系统进行交互。 提供了与计算机程序接口的视频捕捉系统,该计算机程序可用于捕获第一用户的实时视频。 该方法通过识别可以使用捕获的实时视频中的实时效果来修改的第一用户的视频图像的组件来继续。 在另一操作中,该方法识别来自第一用户或第二用户的控制器输入。 识别由计算系统检测到的控制器输入,以确定将修改哪个已识别的第一用户的组件。 响应于所识别的控制器输入,该方法的另一操作通过将实时效果应用于第一用户的所识别的组件来增强第一用户捕获的实时视频。 该方法然后在连接到第一和第二用户中的一个或两个的计算系统的屏幕上显示第一用户的增强实时视频。
