12. The method of claim 11 , further comprising: determining which patches to provide for the signature generation based on at least one of: an entropy level of a patch, corners identified in a patch, and borders identified in a patch.
12. The method of claim 11 , further comprising: determining which patches to provide for the signature generation based on at least one of: an entropy level of a patch, corners identified in a patch, and borders identified in a patch. 16. The method of claim 12 , wherein the at least one signature is generated using a signature generator (SG), wherein the SG comprises a plurality of computational cores, each computational core having properties statistically independent of each other computational core, each computational core generates, responsive to the received MMDE at least one signature, wherein the least one signature is robust to noise and distortions.
