| Abstract: | Aiming at the problem that the protection algorithm based on SIFT had low operating efficiency and algorithm structure was huge,an optimization algorithm based on SIFT face feature protection algorithm was presented.This algorithm improved the efficiency of retrieval by optimizing the data storage and the data structure in the feature database of the original algorithm.The experiment was carried out on the optimized algorithm in AR and YALE face databases,the experimental results showed that the optimization algorithm ensured data security of the premise,kept recognition rate of the original algorithm,at the same time,made the recognition system more efficient. |
