| 摘 要： | 通过分析指纹识别系统的特点和小波分析的特性,在指纹图像初滤波和指纹特征提取方面提出了新见解.小波分析具有良好的空间域和频率域的局部化特性,结合指纹图像高频丰富的特点,采用小波包分析对指纹图像进行初滤波,结合指纹图像类周期的模式,采用多尺度小波变换提取指纹的统计特征,进行预匹配,提高匹配速度.实验结果表明,小波在指纹识别系统中具有较强的实用性.

| Abstract: | The feature of fingerprint identification system and wavelet analysis are analyzed,new approaches for fingerprint preliminary filtering and extracting fingerprint feature are proposed.Wavelet analysis has good time frequency localization,combining with the feature of fingerprint containing abundant high frequency,the fingerprint is filtered preliminarily by means of wavelet package.Combining with the quasi-periodic model of fingerprint,the statistical feature is extracted by means of multi-resolution wavele... |
