论文摘要
在本文中,我们提出了在线手写习得的压力表征和标准化程序。已经在生物识别识别实验(识别和验证)中使用在线签名数据库MCYT对标准化过程进行了测试,该数据库由330位用户的签名组成。目的是分析用户使用一种手写笔的实际不匹配方案,然后使用不同的压力响应的不同手写笔模型生产一些测试样品。实验结果表明:1)压力信号中的饱和行为2)在所研究的不同手写笔中的不同动态范围3)通过压力信号归一化以及不匹配条件下的性能降解改善了生物识别识别精度4)可以通过压力归一化来获得不同手写笔之间的互操作性。与不匹配的情景相比,标准化的签名识别率更高(绝对值)高于7%(绝对值)。
In this paper, we present a pressure characterization and normalization procedure for online handwritten acquisition. Normalization process has been tested in biometric recognition experiments (identification and verification) using online signature database MCYT, which consists of the signatures from 330 users. The goal is to analyze the real mismatch scenarios where users are enrolled with one stylus and then, later on, they produce some testing samples using a different stylus model with different pressure response. Experimental results show: 1) a saturation behavior in pressure signal 2) different dynamic ranges in the different stylus studied 3) improved biometric recognition accuracy by means of pressure signal normalization as well as a performance degradation in mismatched conditions 4) interoperability between different stylus can be obtained by means of pressure normalization. Normalization produces an improvement in signature identification rates higher than 7% (absolute value) when compared with mismatched scenarios.
