When a person passes by a surveillance camera a sequence of image is obtained. Before performing any analysis on the face of a person, the face first needs to be detected and secondary the quality of the different face images needs to be evaluated. In this paper we present a system based on four simple features including out-of-plan rotation, sharpness, brightness and resolution, to assess the ...

Really Simple Syndication (RSS) uses extensive markup language (XML) to constantly scan the content of Web sites for updates, which will then be delivered to subscribers' desktops or mobile devices through an RSS feed. RSS helps professionals stay current while reducing workloads. Librarians need to get familiar with RSS to educate their users, to stay current in information technology, and to ...

It was once taken for granted that learning in animals and man could be explained with a simple set of general learning rules, but over the last hundred years, a substantial amount of evidence has been accumulated that points in a quite different direction. In animal learning theory, the laws of learning are no longer considered general. Instead, it has been necessary to explain behaviour in te...

Introduction / objectives Human memory capacity is limited and even relatively simple concepts are not easily retained if not central to the individual’s emotional engagement. The ‘My five moments for hand hygiene’ (Sax H, et al. J Hosp Infect 2007;67:9-21) has been designed to be simple and ‘sticky’. But even so, as informal surveys show, only 2 of 5 hand hygiene indications are accessible in ...

Taking account of the compositional nature of proportions, the logistic function is the natural transformation to apply when analyzing and modelling time series of continuous proportions. From the metric structure on the simplex, an isomorphic structure is defined on the set of continuous proportions. This structure permits the translation of the standard analysis of univariate time series to t...

The union of every point-finite, completely measurable family of Loeb nullsets is itself a Loeb nullset, provided the nonstandard model satisfies a simple set-theoretic condition. One application of this result is that every Loeb measurable function into a metric space has a lifting.

The development of increasingly complex multimedia applications calls for new methodologies for the organization and retrieval of still images and video sequences. Query and retrieval methods based on image content promise good results, are currently widely investigated and, to some extent, already commercially available. Yet a large number of issues remain unsolved. In this paper we describe s...

BioC is a simple XML data format for text, annotations, and relations. PubAnnotation is a repository of text annotations focused on the life science literature. A conversion tool between BioC XML and the JSON import / export format of PubAnnotation has been developed, BioCconvert. As a demonstration, the Ab3P gold standard abbreviation annotations are being made available through PubAnnotation....

In this paper, we study the human action classification problem based on motion features directly extracted from video. In order to implement a fast classification system, we select simple features that can be obtained from non-intensive computation. We also introduce the new SVM 2K classifier that can achieve improved performance over a standard SVM by combining two types of motion feature vec...

A new generation algorithm for the base-K logarithm is presented. Intermediate results for computation of the logarithm are presented in the redundant signed digit (RSD) representation, and additions and subtractions were performed without carry propagation. Based on the properties of RSD arithmetic, higher performance is obtained as compared with the conventional logarithm in the classical bin...
