Abstract :
The minor expressiveness of text with respect to visual features has determined the prevalence of visual interaction paradigms for specifying queries in systems for image retrieval by content. To cope with user´s subjectivity, the description of image visual contents should exploit different levels of detail in image representation. We present a system which supports image indexing and retrieval based on color regions. The system exploits a pyramidal representation of the images which are segmented at different levels of resolution. Multiple descriptions of image regions are created at different levels of resolution thus allowing effective retrieval through specific queries as well as imprecise ones
