语音前期处理 对采集输入的语音信号进行倒谱分析(Pre-processing of the collected voice input voice signal cepstrum analysis)

National Taiwan Central University开发的HHT算法，基于matlab平台。供大家参考(HHT from National Taiwan Central University base on matlab)

首先生成如下形式的图片：图中的白条为7象素宽，210象素高，白条间的宽度为17象素。 然后应用多种滤波器进行处理：算术均值，几何均值，谐波均值，逆谐波均值，中值滤波，中点滤波，最大值、最小值滤波等。最后详细比较上述的结果，并分析原因。（内含实验报告）(Pictures first generate the following form: in IOUs 7 pixels wide by 210 pixels high, IOUs between the width of 17 pixels. Then apply a variety of filters for processing: arithmetic mean, geometric mean, harmonic mean inverse harmonic mean, median filtering, the midpoint filtering, maximum, minimum filter. Finally, a detailed comparison of the above results, and analyze the reasons. (Contains experimental report))
