中文说明：语音信号的采集与处理，数字信号处理课设，包括回归分析和概率统计，可直接计算得到多重分形谱,采用了小波去噪的思想，独立成分分析算法降低原始数据噪声，多姿态，多角度，有不同光照。
English Description：
Speech signal acquisition and processing, digital signal processing course design, including the idea of regression analysis and probability and statistics, can directly calculate the multifractal spectrum is obtained, using wavelet de-noising and independent component analysis algorithm reduce the raw data noise and multi pose and multi angle, a different illumination.
