1. A method of compressing a block of image elements, each image element having an associated feature vector, said method comprising the steps of: determining at least one parameter representative of a size of a bounding section in a feature vector space encompassing at least a portion of said feature vectors; utilizing said at least one parameter as initial seed for providing a deterministic, pseudo-random pattern of N multiple representation vectors encompassed by said bounding section in said feature vector space; selecting, for at least one image element and based on a feature vector associated with said image element, a representation vector from said N multiple representations vectors as a representation of said feature vector; and assigning, to said at least one image element, a vector identifier associated with said selected representation vector.
