Searching for the exact answer to a similarity query is an expensive process considering computational resources, such as memory and processing time requirements. Moreover, comparison operations over multimedia data is even more expensive than over traditional data such as numbers and small character strings. Therefore, when comparing multimedia data, the(More)
Complex data is usually represented through signatures, which are sets of features describing the data content. Several kinds of complex data allow extracting different signatures from an object, representing complementary data characteristics. However, there is no ground truth of how balancing these signatures to reach an ideal similarity distribution. It(More)
