摘要： A finger sensor may include a plurality of finger image sensing arrays for generating a respective plurality of finger image data sets based upon sliding finger movement over the finger image sensing arrays, and a processor cooperating with the finger image sensing arrays. The processor may determine finger movement based upon the finger image data sets, and generate a resampled finger image data set by resampling the finger image data sets based upon the determined finger movement. The processor may further deskew the finger image data sets when generating the resampled finger image data set.
摘要翻译：手指传感器可以包括多个手指图像感测阵列，用于基于手指图像感测阵列上的滑动手指移动来生成相应的多个手指图像数据组，以及与手指图像感测阵列协作的处理器。处理器可以基于手指图像数据集来确定手指移动，并且基于所确定的手指移动，通过对手指图像数据集进行重新取样来生成重新采样的手指图像数据集。当生成重新采样的手指图像数据集时，处理器可能进一步使手指图像数据组产生偏斜。

摘要： An apparatus and method for enrolling at least one fingerprint and determining a match of a new fingerprint thereto uses data related to fingerprint ridge flow for matching a desired area segment of a new fingerprint to a corresponding area segment stored in a database. The apparatus generates and stores enrollment data based upon fingerprint ridge flow over a plurality of area segments for the at least one fingerprint, senses a new fingerprint, and generates sensed data based upon fingerprint ridge flow of the new fingerprint over at least one desired area segment of the plurality of area segments. The method also preferably includes comparing the enrollment data and sensed data to determine whether the new fingerprint matches an enrolled fingerprint. The generating of sensed data preferably comprises identifying and generating sensed data for only a single desired area segment in one embodiment. In another embodiment, a plurality of area segments are identified and processed to achieve a desired performance.
摘要翻译：用于登记至少一个指纹并确定新指纹的匹配的装置和方法使用与指纹脊流相关的数据，以将新指纹的期望区域段与存储在数据库中的对应区域段进行匹配。该设备基于指纹脊流在多个区域段上生成并存储登记数据，用于至少一个指纹，感测新指纹，并且基于至少一个所需区域段上的新指纹的指纹脊流产生感测数据的多个区域段。该方法还优选地包括比较注册数据和感测数据，以确定新指纹是否匹配登记的指纹。感测数据的产生优选地包括在一个实施例中识别并产生仅一个期望区域段的感测数据。在另一个实施例中，识别和处理多个区域段以实现期望的性能。
