根据手指压力的手指触摸分类方法及指纹感测系统
Abstract:
一种根据手指压力对指纹传感器(3)的表面上的手指触摸进行分类的方法，包括以下步骤：在指纹传感器的表面上接收(100)具有指纹形貌的手指；获取(101)第一指纹图像时间序列；基于第一指纹图像时间序列中的至少一个指纹图像，确定(102)指示指纹形貌的压缩的至少一个图像相关参数的参考值；获取(106)第二指纹图像时间序列；基于第二指纹图像时间序列中的至少一个指纹图像确定(107)至少一个图像相关参数的测试值；以及基于测试值与参考值之间的关系对手指触摸进行分类(109)。
Abstract(English):

A method of classifying a finger touch in respect of a finger pressure on a surface of a fingerprint sensor(3), comprising the steps of: receiving(100), on the surface of the fingerprint sensor, a finger having a fingerprint topography; acquiring(101)a first time-sequence of fingerprint images; determining(102)a reference value of at least one image-related parameter indicative of a compression ofthe fingerprint topography, based on at least one fingerprint image in the first time-sequence of fingerprint images; acquiring(106)a second time-sequence of fingerprint images; determining (107)a test value of the at least one image-related parameter based on at least one fingerprint image in the second time-sequence of fingerprint images; and classifying(109)the finger touch based on a relationbetween the test value and the reference value.
