ABSTRACT:
The present invention provides a technique for retrieving pictures from a large database that is less complex and uses significantly less memory and computational resources than current techniques. This is accomplished by determining representative data vectors based on a tolerance distance that represents data vectors in a given vector space that defines the picture to extract features of the picture that facilitates in retrieving pictures.
