Surveillance of public environments, and in particular of museum rooms, is an important activity that requires the use of different computer and telecommunication technologies. In this paper we describe a semi-automatic surveillance system that is based on a 3D reconstruction of a museum environment, obtained by a stereo vision system, that allows for detecting those situations that are conside...

This paper describes an automatic target recognition system for detecting targets in temporal sequences of intensity LADAR images. The system rst nds all objects in the images using a general method that is capable of nding both blobs and curves. Then features of the objects are extracted. Next fuzzy c-means is used to cluster the objects in feature space. Finally, prototypes generated for each...

Network coding (NC)-enabled mobile small cells are observed as a promising technology for 5G networks in cost-effective and energy-efficient manner. The NC-enabled environment suffers from pollution attacks where malicious intermediate nodes manipulate packets transition. Detecting the polluted well identifying exact location of users equally important tasks these networks. SpaceMac (Le & Marko...

An important aspect of distinctive feature based approaches to automatic speech recognition is the formulation of a framework for robust detection of these features. We discuss the application of the support vector machines (SVM) that arise when the structural risk minimization principle is applied to such feature detection problems. In particular, we describe the problem of detecting stop cons...

Stemming is a common method for morphological normalization of natural language texts. Modern information retrieval systems rely on such normalization techniques for automatic document processing tasks. High quality stemming is difficult in highly inflectional Indic languages. Little research has been performed on designing algorithms for stemming of texts in Indic languages. In this study, we ...

Many sequences of p-adic integers project modulo p to p-automatic sequences for every α ≥ 0. Examples include algebraic sequences of integers, which satisfy this property for every prime p, and some cocycle sequences, which we show satisfy this property for a fixed p. For such a sequence, we construct a profinite automaton that projects modulo p to the automaton generating the projected sequenc...

Many languages have a non-obvious, but not unrelated, relationship between orthography and pronunciation. Traditional methods for automatic conversion from letters to phones involve hand-crafted letter-to-sound rules, but these require care and expertise to develop. This paper presents a letter-to-sound rule system for Thai, that is trained automatically from lexicons. A statistical model, deci...

Previous studies have shown that letter repetitions are detected more rapidly when presented bilaterally (one letter in each visual field) than when presented unilaterally (both in the same field) when subjects have to report matches independently of case or font (e.g., Aa). This pattern of results is referred to as a bilateral field advantage. Here, we present evidence of an opposite pattern o...
