Electronic device, image-based age classification method and storage medium

Abstract

The invention discloses an electronic device, an image-based age classification method and a storage medium, comprising: after receiving a first human face image whose age is to be identified, cutting the first human face image by using a preset cutting rule , to obtain a preset number of second human face images; use a predetermined human face image recognition model to carry out age recognition on the second human face images, and generate age feature vectors corresponding to each second human face images; each age feature vector Perform mean value processing to obtain the average age feature vector; use a predetermined age classification function to carry out age classification analysis on the average age feature vector to obtain the average age type corresponding to the second face image, and the average age type is the first face image corresponding age type. In this way, the problems of large amount of calculation and low efficiency in the face recognition model training process can be effectively avoided, and the accuracy of age classification based on face images can also be improved.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to an electronic device, an image-based age classification method and a storage medium. Background technique [0002] In recent years, with the development of face recognition technology, users have higher and higher requirements for face image recognition. According to the identified age groups, user preferences of different age groups, and popularity of products by users of different age groups are collected. [0003] At present, the commonly used face recognition technology needs to obtain a sample set composed of multiple face images for multi-age classification before performing age classification based on the face image, and use the samples that meet the current age group as the positive sample set. The samples of the age group are used as negative sample sets for training to generate a face image recognition model for age classification based on face images. Usually, the num...
