Introduction

The quality of the fingerprint image data is defined as the predicted behavior of the image in a matching environment. So in many applications quality information is crucial important. GB/T 30267.1-2013 and GB/T 28826.1-2012 assign a quality domain to the quality score and specify the allowable Range of scores. According to the recommendations in these criteria, the quality score will be subdivided into four categories, each corresponding to a qualitative interpretation. in The same definition in the standardized fingerprint data exchange format of GB/T 26237.2, GB/T 26237.3, GB/T 26237.4, GB/T 26237.8 Image quality domain. However, at present, there is no standard quality score definition method that helps explain and exchange fingerprint image scores. This section is a recommended standard for a guiding method that seeks to express and interpret the fingerprint image quality in an objective and quantitative manner. The number method; at the same time, it supplements ISO /IEC 29794-1 in the development of reference fingerprint image data sample libraries. This reference sample The library is based on the availability of public fingerprint images and can subsequently be used to regularize the quality scores.
