Conventional approaches to sampling signals or images follow Shannon's theorem: the sampling rate must be at least twice the maximum frequency present in the signal (Nyquist rate). In the field of data conversion, standa...

Webservices technology is one of the stilts on which the concept WEB 2.0 is sustained. This technology allows to send information between computers connected to the network, providing a high portability level communicati...

Digital repositories acting as resource aggregators typically face different challenges, roughly classified in three main categories: extraction, improvement and storage. The first category comprises issues related to de...

The algorithmical architecture and structure is presented for the parallelization of image similarity analysis, based on obtaining multiple digital signatures for each image, in which each "signature" is composed by the ...
