Firstly gain the continuously directional image of the fingerprint, secondly design orientation template using the directional image and filter the fingerprint image, lastly obtain the binary image.───先得到指纹图像的连续方向图，再根据此方向图设计方向滤波模板进行滤波，最后得到指纹的二值化图像。

Firstly, feature vectors are extracted from speech signal, secondly, vector quantization is utilized to design code book, and lastly, improved method is used to recognize the speech signal.───先从语音信号中提取待识别的特征矢量集，再利用矢量量化来设计码本，最后用改进的算法对待识别语音进行辩识。
