:由于许多传统的去噪方法在强背景噪声情况下提取声音信号的能力变弱甚至失效, 提出
应用独立成分分析( I C A) 方法对声音信号进行特征提取, 并证明了这种 I C A 变换能增强语音和音
乐信号的超高斯性. 在此基础上, 应用 I C A基函数作为滤波器, 通过阈值化的去噪方法对含有强高
斯背景噪声的声音信号进行去噪仿真实验. 结果表明, 本方法明显优于传统的均值滤波和小波去噪
方法, 为强背景噪声下弱信号的检测提供 了新的途径.-: As many of the t

该方法利用人脸具有镜像对称的自然特性,依据奇偶分解原理,生成成镜像奇、偶对称样本,井利用人脸对称图像作为训练样本,再利用主分量分析(PCA)对训练样本进行二阶相关和降维处理,然后对处理后的样本进行ICA特征提取。理论和分析实验证明,该算法有效减线了人脸受到视角、光照、人脸表情、姿势变化等因素的最响,又增加了训练样本容量,减少了计算复杂度,同时有效解决了小样本问题,提高了识别率.(The method uses the natural characteristics of mirror symme
