Document Type and Number:
WIPO Patent Application WO/2021/174875
Kind Code:
A1
Abstract:
The present application provides a face feature vector dynamic adjustment method and a related device. The method comprises: determining, according to face image acquisition time corresponding to face feature vectors of a user in a preset database, weights of the face feature vectors of the user in the preset database, and calculating, according to the weights, a weighted average value of the face feature vectors of the user in the preset database; calculating an expected face feature vector sequence of face feature vectors corresponding to the latest time in the face image acquisition time of the user in the preset database; determining a preferred face feature vector of the user from the face feature vectors of the user in the preset database according to the expected face feature vector sequence and the weighted average value; calculating a new face feature vector of the user according to the preferred face feature vector of the user; and updating the matching face feature vector in a face feature library according to the new face feature vector. According to the present application, the sustainability of a face recognition task is enhanced. Moreover, the present application also relates to a block chain.
