Abstract: A method and an apparatus for fingerprint recognition are provided. The method is applied to the field of fingerprint recognition technologies. The method includes: acquiring a to-be-verified fingerprint image; determining a first eigenvector based on the to-be-verified fingerprint image, where the first eigenvector is obtained by performing dimensionality reduction processing on a second eigenvector using a first orthogonal matrix, and the second eigenvector is used to represent a feature of the to-be-verified fingerprint image; and performing fingerprint matching based on the first eigenvector and a third eigenvector, where the third eigenvector is obtained by performing dimensionality reduction processing on a fourth eigenvector using the first orthogonal matrix, the fourth eigenvector is used to represent a feature of a first fingerprint template, and the third eigenvector is stored in a fingerprint template library.

Abstract: A fingerprint recognition method and apparatus are provided. The method is applied to the field of fingerprint recognition technologies. The method includes: when a first fingerprint image is successfully matched, judging whether matching information of the first fingerprint image satisfies a first preset condition; when the matching information of the first fingerprint image satisfies the first preset condition, judging whether a cumulative update count of a second fingerprint template is greater than a first quantity threshold; when the cumulative update count of the second fingerprint template is greater than the first quantity threshold, judging whether priority information of the second fingerprint template satisfies a second preset condition; and when the priority information of the second fingerprint template satisfies the second preset condition, updating the second fingerprint template with the first fingerprint image. A high-quality fingerprint image is selected through a plurality of judgment conditions to update a fingerprint template library. Matching is performed based on an updated fingerprint template library. This can increase a fingerprint unlocking rate and an unlocking speed, so that user experience in unlocking is improved.
