A new approach for fuzzy feature extraction based on pixel´s brightness

In this paper we propose a feature extraction method based on brightness control of the pixels of an image using a fuzzy logic inference system. The proposed method was used in a hybrid pattern recognition system of the fingerprints, to improve the identification rate. The fuzzy extraction method preprocesses the fingerprint images and adjusts the brightness. The obtained image is input to the ensemble neural network (ENN), the ENN output is based on response integration with type-1 and type-2 fuzzy logic to obtain the fingerprint identification.
