一种基于移动平台的掌纹ROI定位算法

摘要

With the advent of the era of mobile information,the demand for the application of algorithm running on mobile platform is becoming more and more urgent.In the past,most palmprint location algorithms are proposed for fixed acquisition equipment,we present a fast location algorithm of Haarp almprint ROI based on mobile platform,which integrated consideration the morphological features and texture features of the valley points between fingers to improve the accuracy of positioning.The results of experiments shows,the algorithm has good localization accuracy and with a faster running speed on mobile devices.%随着移动信息时代已经到来,对于适用于移动平台的掌纹ROI定位算法的需求日益迫切.针对以往大多数掌纹定位算法均针对固定采集设备提出,本文提出了一种基于移动平台的掌纹ROI快速定位算法,该算法综合考量指间谷点附近的形态学特征和纹理特征从而提高定位的准确度.实验结果表明,该算法具有较好的定位精度,并且在移动设备上仍具有较快的运行速度.
