Hybrid face recognition, using image (2D) and structural (3D) information, has explored the fusion of Nearest Neighbour classifiers. This paper examines the effectiveness of feature modelling for each individual modality, 2D and 3D. Furthermore, it is demonstrated that the fusion of feature modelling techniques for the 2D and 3D modalities yields performance improvements over the individual cla...

This paper presents a method for automatic real time face and mouth recognition using radial basis function neural networks (RBFNN). The proposed method uses the motion information to localize the face region, and the face region is processed in YCrCb color space to determine the locations of the eyes. The center of the mouth is determined relative to the locations of the eyes. Facial and mouth...

Imipenem is a member of a new class of highly potent beta-lactam antibiotics, carbapenems, with a very broad antibacterial spectrum. This study was undertaken to determine tentative interpretive criteria for in vitro susceptibility testing with 10-micrograms imipenem disks. A careful examination of the zone diameters and the corresponding MICs for 489 clinical isolates by regression-line analys...

in the present study iran’s rice imports trend is forecasted, using artificial neural networks and econometric methods, during 2009 to 2013, and their results are compared. the results showed that feet forward neural network leading with less forecast error and had better performance in comparison to econometric techniques and also, other methods of neural networks, such as recurrent networks a...

since gait is the mixture of many complex movements, each individual can define with a unique footpressure image that can be used as a reliable biometric scale for human verification. foot pressure colorimages of center for biometrics and security research (cbsr) dataset from 45 men and five womenwere used in this study. owing to the properties of this dataset, an index of foot pressure in addi...

A measure of closeness among three or more means from normal populations was proposed by Ng (2000). The F-statistic was proposed to test the null hypothesis that this measure of closeness is greater than or equal to some prespecified δ (>0), against the alternative hypothesis that this measure of closeness is smaller than δ. The null distribution of the F-statistic at the boundary has a non-cen...

in this paper, the effects of scintillation phenomena on bit error rate (ber) and signal to noise ratio (snr), which are essential characteristics in free space optical (fso) communication system, are studied. until now various methods have been introduced to decrease ber and increase the link's reliability. optimizing snr is one of the fundamental methods to decrease ber value. intensity fluct...

This paper studies the relationship between word error rate (WER) and keyword error rate (KER) in speech transcripts and their effect on the performance of speech analytics applications. Automatic speech recognition (ASR) systems are increasingly used as input for speech analytics, which raises the question of whether WER or KER is the more suitable performance metric for calibrating the ASR sy...
