In recent years, the remote-sensing community has became very interested in applying neural networks to image classification and in comparing neural networks performances with the ones of classical statistical methods. These experimental comparisons pointed out that no single classification algorithm can be regarded as a ?panacea?. The...

The common operation mechanism of multiple classifier systems is the combination of classifier outputs. Some researchers have pointed out the potentialities of "dynamic classifier selection" as an alternative operation mechanism. However, such potentialities have been motivated so far by experimental results and qualitative arguments. This...

High retrieval precision in content-based image retrieval can be attained by adopting relevance feedback mechanisms. These mechanisms require that the user judges the quality of the results of the query by marking all the retrieved images as being either relevant or not. Then, the search engine exploits this information to adapt the search to...

Nowadays an increasing number of commercial and public services are offered through the Internet, so that security is becoming a key issue. The so-called ?attacks? on Internet service providers are carried out by exploiting both unknown weaknesses or bugs that are always contained in system and application software, and complex unforeseen...
