Proximity queries consists in retrieving objects near a given query. To avoid a brute force scan over a large database, an index can be used. However, for some problems, indexes are mostly useless (their running times are worst than sequential scan). On the other hand, researchers have tried massively parallel hardware (as GPGPU) in the quest of fa...

Query-by-content by means of similarity search is a fundamental operation for applications that deal with multimedia data. For this kind of query it is meaningless to look for elements exactly equal to the one given as query. Instead, we need to measure dissimilarity between the query object and each database object. The metric space model is a par...

Image mining deals with the study and development of new technologies that allow accomplishing this subject. A common mistake about image mining is identifying its scopes and limitations. Clearly it is different from computer vision and image processing areas. Image mining deals with the extraction of image patterns from a large collection of image...

Los sistemas diseñados para resolver pro-blemas específicos como los procesadores gráfi-cos(GPU), tienen características muy atractivas (bajo precio en relación a su potencia de cálcu-lo, gran paralelismo, optimización para cálculos en coma flotante, entre otras) para su uso en apli-caciones de propósito general, en problemas rela-cionados aí ambit...

Retrieving audio signals by content in large repositories require a stable and persistent representation of the audio. Such a representation is called an Audio Fingerprint (AFP). A robust AFP should be an invariant of the audio signal and it should represent the signal despite severe degradations it may suffer. The robustness of the AFP is inversel...
