Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] see figure 1 , figure 1 What is shown is a schematic flowchart of a method for age prediction of a face image provided by an embodiment of the present invention. combine figure 1 It can be seen that the age prediction method includes:

[0029] Step 101: Divide the ages contained in the preset age set into multiple age groups according to the preset similar age grouping rule.

[0030] Wherein, the preset age set can be set according to actual needs, for example, in some optional embodiments, the preset age set is recorded as Y={l 0 , l 1 ,...,l k}, where l 0 , l 1 ,...,l k For the preset age set Y={l 0 , l 1 ,...,l k} contained in the age, l 0 1 k , k is a positive integer.

[0031] During specific implementation, the process of dividing the ages contained in the preset age set into multiple age groups according to the pres...

Abstract

The invention discloses a method and device for age prediction of a face image. The age prediction method includes: dividing the age contained in the preset age set into multiple age groups according to the preset similar age grouping rules; determining the training face image and the multiple age groups according to the age of the training face image The matching relationship of each age group in the above; according to the matching relationship, use the training face image to train the preset age group classification network to generate a convergent age group classification network; use the convergent age group classification network to predict to be detected The target matching probability of the human face image and each age group; predicting the age of the human face image to be detected according to the target matching probability. The age prediction method does not destroy the correlation between similar ages, the age prediction result of the face image to be detected is more accurate, and the applicability is better.

Description

technical field [0001] The present invention relates to the technical field of face image recognition, in particular to a method and device for age prediction of a face image. Background technique [0002] Usually, the aging process of a person is affected by many factors, such as: genes, external environment, daily life and diet, etc. These factors cause the aging rate of each person to be different. At the same time, the aging process of a person is a relatively slow process. Therefore, The features of the same person or different people at similar ages are relatively similar, so that the facial features of the face images of the same person or different people at similar ages are relatively similar. [0003] In the prior art, in the age prediction technology of face images, age is usually regarded as a separate category. When training a network model for predicting the age of face images, the training face images of known age are combined with age Establish a one-to-one ...
