The importance of speaking style authentication from human speech is gaining an increasing attention and concern from the engineering community. The importance comes from the demand to enhance both the naturalness and efficiency of spoken language human-machine interface. Our work in this research focuses on proposing, implementing, and testing speaker-dependent and text-dependent speaking styl...

Research has shown that observers in a multiple-object tracking task are poor at recognizing the identity of successfully tracked objects (Z. W. Pylyshyn, 2004). Employing the same paradigm, we examined identity processing and its relationship with tracking performance for human faces. Experiment 1 showed that although identity recognition was poorer after the target faces were learned in a dyn...

Identification of fossil material under a microscope is the basis of micropalentology. Our task is to locate and count the pieces of inertinite and vitrinite in images of sieve sampled rock. The classical watershed algorithm oversegments the objects because of their irregular shapes. In this paper we propose a method for locating multiple objects in a black and white image while accounting for ...

The voice is a marker of a person's identity which allows individual recognition even if the person is not in sight. Listening to a voice also affords inferences about the speaker's emotional state. Both these types of personal information are encoded in characteristic acoustic feature patterns analyzed within the auditory cortex. In the present study 16 volunteers listened to pairs of non-verb...

Although different brain regions are widely considered to be involved in the recognition of facial identity and expression, it remains unclear how these regions process different properties of the visual image. Here, we ask how surface-based reflectance information and edge-based shape cues contribute to the perception and neural representation of facial identity and expression. Contrast-revers...

An effective programming style for gesture signal processing is described using a new library that brings efficient run-time polymorphism, functional and instance-based object-oriented programming to Max/MSP. By introducing better support for generic programming and composability Max/MSP becomes a more productive environment for managing the growing scale and complexity of gesture sensing syste...

In cognitive radio, the cooperative spectrum sensing (CSS) plays a key role in determining the performance of secondary networks. However, there have not been feasible approaches that can analytically calculate the performance of CSS with regard to the multi-level quantization. In this paper, we not only show the cooperative false alarm probability and cooperative detection probability impacted...

We present below our first implementation results on a modular arithmetic library for cryptography on GPUs. Our library, in C++ for CUDA, provides modular arithmetic, finite field arithmetic and some ECC support. Several algorithms and memory coding styles have been compared: local, shared and register. For moderate sizes, we report up to 2.6 speedup compared to state-of-the-art library.

Speech carries both linguistic content – phonemes, words, sentences – and talker information, sometimes called ‘indexical information’. While talker variability materially affects language processing, it has historically been regarded as a curiosity rather than a central influence, possibly because talker variability does not fit with a conception of speech sounds as abstract categories. Despit...
