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 an age prediction method and device for a face image. The method comprises a step of dividing ages included in a preset age set into a plurality of age groups according to a preset similar age grouping rule, a step of determining a matching relationship between the training face image and each age group in the plurality of age groups according to the age of the training face image, a step of training the preset age group classification network by using the training face image according to the matching relationship and generating a convergence age group classification network, a step of predicting a target matching probability of a face image to be detected and each age group by using the convergence age group classification network, and a step of predicting the ageof the face image to be detected according to the target matching probability. According to the age prediction method, the correlation between similar ages is not destroyed, the age prediction resultof the face image to be detected is more accurate, and the applicability is good.

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 ...
