Fuzzy pattern recognition method applied in droplet fingerprint recognition

In this paper, fuzzy pattern recognition has been applied to the identification of droplet fingerprint which is taken as the research object. The identification based on the features extracted from droplet fingerprint and the establishment of membership functions. Then, identify the liquid by using the fuzzy identification theory to select features and matching based on classification of features. The experiments proved that the fuzzy pattern recognition method can not only effectively enhance the recognition efficiency, but also can quickly identify the type of liquid.
