针对当前生物测量学中签名鉴定方法发展的要求,基于光学微小角度检测和压电陶瓷(PZT)微力检测原理,研制了一种多参数签名鉴定电笔原型。该笔能检测X、Y向的运笔特征和Z向的笔迹力,沿笔轴的Z向检测采用PZT力传感器,对X和Y向的检测采用二维(2-D)角度传感器检测笔管对应X和Y坐标书写力的2-D倾斜角。为了使电笔的结构更加紧凑、移动更加灵活和仿真性强,采用无线传输的方式将所采集的信号传到PC机上处理验证。对汉字笔画和字母进行了三维(3-D)特征检测的可行性验证试验。结果表明,该方法具有可行性,并为笔迹识

提出了一种基于点对线性近似的多数据流自适应分段算法,即快速点对线性近似的时序流(QPLAS)算法,它能够实时地对多数据流进行分段.采用一次扫描和滑动窗口工作机制,其主要思想是增量计算方法,能够在O(1)的时间复杂度内连续计算每个段的近似错误.为了同时处理多个数据流分段,将所有数据流当前未完成的段索引到一个B+树索引当中.这样,QPLAS仅占用少量内存即可高效处理多个数据流的分段.实验结果表明QPL
