Texture Feature Extraction Using Hybrid Wavelet Type I & II for Finger Knuckle Prints for Multi-algorithmic Feature Fusion

Abstract

The finger knuckle print (FKP) of a particular person is found to be unique and can serve as a biometric feature has been revealed recently by the researchers. In this research Finger Knuckle Print has been used as a biometric feature. Hybrid Wavelet Type I and Hybrid Wavelet Type II were used for feature extraction from the images in order to process it further. The important role of hybrid wavelet transform is to combine the key features of two different orthogonal transforms so that the strengths of both the transform wavelets are used. In this research the different transforms like (Discrete Cosine Transform) DCT, Haar. Hartley, Walsh and Kekre are used in combination for generation of 20 different hybrid wavelets. These hybrid wavelets are applied on the database images to generate feature vector coefficients and they are then subjected to Intra Class testing And Inter Class Testing and their performance is evaluated and compared. Proposed system has given up to 77% of EER for TAR-TRR (PI) for multi-algorithmic implementation of HWI+HWII.
