Examples

  1. According to the fact that the basic features of apalmprint , including principal lines , wrinkles and ridges , havedifferent resolutions , in this paper we analyze palmprints using amulti - resolution method and define a novel palmprint feature , whichcalled wavelet energy feature , based on the wavelet transform . wef can reflect the wavelet energy distribution of the principal lines , wrinkles and ridges in different directions at different resolutions scales , thus it can efficiently characterize palmprints . this paperalso analyses the discriminabilities of each level wef and , according to these discriminabilities , chooses a suitable weight for each levelto compute the weighted city block distance for recognition . theexperimental results show that the order of the discriminabilities ofeach level wef , from strong to weak , is the 4th , 3rd , 5th , 2nd and 1stlevel
    作为对现有人体生物特征识别技术的重要补充,掌纹识别有着其独特的优点:掌纹比指纹含有更多的可区分信息掌纹采集设备的价格比虹膜采集设备的价格要低廉得多掌纹特征比签名特征更为稳定掌纹识别可获得比人脸识别更高的识别精度掌纹含有独特的线特征包括主线和皱褶,这些线特征具有很强的区分能力,并可以在低分辨率图像中提取出来可以将手掌上的各种特征融合在一起建立一个高精度的生物识别系统等。
