Abstract

The invention discloses a fingerprint retrieval method based on sweat pore features and a neural network. The method comprises the following steps: acquiring a fingerprint image; extracting global features of the fingerprint image and sweat pore features of the fingerprint image based on a trained feature extraction model; and screening and matching the fingerprint image for a plurality of times according to the global features of the fingerprint image and the sweat pore features of the fingerprint image to obtain a retrieval result of the fingerprint image. The global feature and the sweat pore feature of the fingerprint image are extracted, the fingerprint image is screened and matched for multiple times based on the two features, and the feature information can be effectively extracted by the feature extraction model due to rich sweat pore features, so that the fingerprint image retrieval speed and precision are improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a fingerprint retrieval method based on sweat pore features and a neural network. Background technique [0002] Fingerprint Retrieval Fingerprint Retrieval is to search for fingerprint pictures similar to the input fingerprint from a fingerprint library to determine the identity of the input fingerprint image. Traditional fingerprint recognition algorithms use minutiae features to search for the most similar fingerprint list to the input fingerprint image through image retrieval technology, but when minutiae faces fingerprint fragments, fingerprint retrieval often fails due to insufficient number of feature points. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a fingerprint retrieval method based on sweat pore features and n...
