We propose to use binary strings as an efficient feature point descriptor, which we call BRIEF. We show that it is highly discriminative even when using relatively few bits and can be computed using simple intensity difference tests. Furthermore, the descriptor similarity can be evaluated using the Hamming distance, which is very efficient to compute, instead of the L2 norm as is usually done. ...

The long-term goals are to understand surf zone processes related to rip current systems through field observations. Rip currents occur commonly on most beaches and dominate many. It is recognized that beaches with straight and parallel contours are not a stable morphologic configuration whereas more complex beaches, which support the existence of rip current morphology, are stable and more com...

There is a serious problem with one of the assumptions made in the security proof of the SURF scheme. This problem turns out to be easy in the regime of parameters needed for the SURF scheme to work. We give afterwards the old version of the paper for the reader’s convenience.

The skyline, or Pareto, operator selects those tuples that are not dominated by any others. Extending relational systems with the skyline operator would offer a basis for handling preference queries. Good algorithms are needed for skyline, however, to make this efficient in a relational setting. We propose a skyline algorithm, SFS, based on presorting that is general, for use with any skyline q...

Large numbers of people all over the world read and contribute to various review sites. Many contributors are understandably concerned about privacy in general and, specifically, about linkability of their reviews (and accounts) across multiple review sites. In this paper, we study linkability of community-based reviewing and try to answer the question: to what extent are ”anonymous” reviews li...

Sir,?Since I perused the letter of Baboo Amrito Lall Deb, in your issue of November last, about the beneficial effect of "Amranthus Spinosa" (Kanta Nuteeya) root in Go n orrhoea, I had a strong desire to put it into my practice. As long as I was in charge of the charitable dispensary at .Teh anabad in Gya district I had seen many cases of gonorrhoea, but after a careful investigation I could pr...

Do They Find You on Facebook? Facebook Profile Picture and Hiring Chances* We investigate whether the publicly available information on Facebook about job applicants affects employers’ hiring decisions. To this end, we conduct a field experiment in which fictitious job applications are sent to real job openings in Belgium. The only characteristic in which these candidates differ is the unique F...

The unprecedented popularity of the social networking site Facebook raises a number of important questions regarding the impact it has on sociality. However, as Facebook is a very recent social phenomenon, there is a distinct lack of psychological theory relating to its use. While research has begun to identify the types of people who use Facebook, this line of investigation has been limited to...

The coastal system consists of a sub-aqueous and a sub-aerial zone which can be separated by a border. At this border sediment exchange takes place from one zone to the other. This paper hypothesizes that conditions and therefore sediment exchange at this border are dependent on active profile characteristics. To analyze morphological developments due to combined marine and aeolian processes da...
