说明: 预处理工具包括:主成分Analysi 小号(PCA),白化,过滤:高通滤波(HPF),低通滤波(LPF),子带滤波器(巴特沃斯,切比雪夫,椭圆)用的滤波器,频率子带和可调顺序子带的数量)或用户定义的 预处理功能。
后处理工具实际上包括:通过去除不想要的组件,噪声或伪像,对原始原始数据进行压缩和重建(“清理”)。
该算法不仅可以执行ICA,还可以执行二阶统计盲源分离(BSS),稀疏分量分析(SCA),非负矩阵分解(NMF),平滑分量分析(SmoCA),因子分析(FA)和任何其他可能的矩阵X = HS + N或 Y = WX形式的因式分解,其中H = W +是混合矩阵或基本向量矩阵。X是观测数据的矩阵,S是原始数据的矩阵,N表示其他噪声的矩阵。
ICA / BSS算法是纯数学公式,功能强大,但机械程序却很复杂:机械得到最佳实施后,用户要做的工作不多。ICALAB的成功和有效使用在很大程度上取决于先验知识,常识以及对预处理和后处理工具的适当使用。(icalab toolboxes for signal process, based on the software MATLAB.)

A sound source can be localized in a two dimensional plane using the audio recorded at three known microphone locations. Much like a GPS system, Time Difference of Arrival algorithms can be used to determine the difference in time and distance of a sound source to other microphones. With that information a Chan algorithm can be used to determine the X Y coordinates of the originating sound source. To do so, however, you must first provide the XY coordinates of each of the 3 microphones. Note that for faster and simpler calculation one of the microphones should be placed at the origin (0, 0) of you XY plane.

DPsearch
This code implements the search algorithms described in [1]. The code only contains the Dirichlet/Multinomial case, but the Gaussian case can be hacked in in about 5 minutes.
