In this paper, following the model-free approach for gait image representation, an individual recognition system is developed using the Gait Energy Image (GEI) templates. The GEI templates can easily be obtained from an image sequence of a walking person. Low dimensional feature vectors are extracted from the GEI templates using Principal Component Analysis (PCA) and Multiple Discriminant Analysis...
This paper presents new operators named as linguistic reweighted arithmetic averaging (LRAA) and linguistic reweighted geometric averaging (LRGA) to aggregate information in group multi criteria decision making problems under linguistic settings. These operators are equipped with a capacity to deduce weight of a criterion in commensuration with its ability to discriminate among the alternatives. The...
The reliability of fingerprint matching system is highly depends on the perfect alignment algorithm and a suitable matching techniques, which assign a label to the input fingerprint image. In this paper, we propose a rotation invariant fingerprint descriptor and a improved generalization performance classifier. The proposed new descriptor is represented by a histogram of local directional pattern...
This paper presents three novel methods for speaker identification of which two methods utilize both the continuous density hidden Markov model (HMM) and the generalized fuzzy model (GFM), which has the advantages of both Mamdani and Takagi–Sugeno models. In the first method, the HMM is utilized for the extraction of shape-based batch feature vector that is fitted with the GFM to identify the speaker...
This paper presents an approach for finger knuckle print (FKP's) authentication using DAISY descriptor on different knuckle combinations. Score level fusion is applied on scores of features extracted from FKPs. An improved identification rate is achieved after fusion as compared to that from the individual knuckle print. There has also been a little effort on study of feature selection. The entropy...
