A computer-implemented method of processing a query vector (101) and a data vector (102), comprising: generating a set of masks and a first set of multiple signatures (104) and a second set of multiple signatures (105) by applying the set of masks to the query vector and the data vector, respectively, and generating candidate pairs, of a first signature and a second signature, by identifying matches of a first signature and a second signature. The set of masks comprises a configuration of the elements that is a Hadamard code; a permutation of a Hadamard code; or a code that deviates from a Hadamard code or a permutation of a Hadamard code in less than 40% of its elements. |
