Face feature processing method and device, and storage medium

Abstract

The invention discloses a face feature processing method and device, and a storage medium. The face feature processing method comprises the following steps: carrying out feature extraction on a to-be-identified face object in a target image to obtain an original feature vector of a first data type; performing normalization processing on the original feature vector to obtain a first feature vector;performing conversion processing on the first feature vector according to a first type conversion relation to obtain a second feature vector of a second data type, the storage space occupied by the second feature vector being smaller than the storage space occupied by the original feature vector; obtaining a pre-stored target feature vector of the target face object, and comparing the second feature vector with the target feature vector to obtain the similarity between the to-be-identified face object and the target face object; and under the condition that the similarity is greater than a first target threshold, determining the to-be-identified face object as a target face object. According to the invention, the technical problem of high cost for processing the face features in the priorart is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method, device and storage medium for processing human face features. Background technique [0002] At present, when processing face features, it is necessary to train a deep network model, and compress the face features by modifying the feature output dimension of the deep network model, for example, reducing the 1024-dimensional face feature to a 256-dimensional human facial features. [0003] Although the above method can realize the compression of facial features, the switching of feature dimensions requires retraining of the deep network model, which greatly increases the cost of processing facial features. [0004] For the above-mentioned problem of high cost of processing facial features, no effective solution has been proposed yet.
