spatial correspondence A systematic relationship falling short of registry between the unimodal receptive field locations in individual multimodal neurons. Correspondence can also occur between the receptive fields of neighboring unimodal neurons that respond to different modalities. linear function A function f(x)1⁄4mx, wherem is a constant. Linear functions have the property of superimposibil...

Multimodal biometrics system becomes an inexorable trend in future. Multimodal biometrics overcomes many drawbacks over unimodal biometrics. Some of the drawbacks are non-universality, noisy data and spoof attack. Multimodal biometric is more efficient and accurate than unimodal system. In this paper we present a multimodal biometric recognition system using Iris and finger Inner-knuckle print....

Most biometric systems deployed in real-world applications are unimodal. Using unimodal biometric systems have to contend with a variety of problems such as: Noise in sensed data; Intra-class variations; Inter-class similarities; Nonuniversality; Spoof attacks. These problems have addressed by using multibiometric systems, which expected to be more reliable due to the presence of multiple, inde...

This research examined the developmental course of infants' ability to perceive affect in bimodal (audiovisual) and unimodal (auditory and visual) displays of a woman speaking. According to the intersensory redundancy hypothesis (L. E. Bahrick, R. Lickliter, & R. Flom, 2004), detection of amodal properties is facilitated in multimodal stimulation and attenuated in unimodal stimulation. Later in...

A Bayesian nonparametric method for unimodal densities on the real line is provided by considering a class of species sampling mixture models containing random densities that are unimodal and not necessarily symmetric. This class of densities generalize the model considered by Brunner (1992), in which the Dirichlet process is replaced by a more general class of species sampling models. A novel ...

Although vector strength (VS) and the Rayleigh tests are widely used to quantify neuronal firing synchrony to cyclic events, their use is valid only for singly peaked, unimodal distributions. In this report, we propose a new method to quantify synchrony, applicable to both unimodal and multimodal distributions. We also propose a statistical test to examine temporal structure under a null hypoth...
