Problems solved by technology

However, most of the research is based on existing data sets. Because there are too few samples of yellow, brown and other races in many existing large-scale foreign data sets, the age recognition of yellow, brown and other race pictures is greatly limited.

Embodiment Construction

[0034] DRAWINGS Examples and further detailed description of the present invention, the following Examples are intended to explain the present invention and the present invention is not limited to the following embodiments.

[0035] Generated against the network (GAN) generated by a model consisting of G and D discriminant model, by way of learning against the number of training set and a new data sample. 2014 Goodfellow published "Generative Adversarial Networks" article, the formula against the network debut in academia, the main idea from game theory (that is, the interests of the two is zero, resulting in one of the official party to the loss). Since then, GAN is applied to solve practical problems, such as the study of language problems, speech processing, chess competition procedures. Generating model captures G data distribution of the sample, with a subject distribution (uniform, Gaussian, etc.) to generate a noise sample z a real similar training data, the effect is more ...

Abstract

The present invention discloses a face age estimation method based on GAN extended multi-ethnic feature cooperative selection. Firstly, the multi-style face samples are simulated and generated through the generative confrontation network, so as to quickly and large-scale expand the faces of different races. Face database, so as to improve the accuracy of age information recognition of yellow, brown and other races. Then use the convolutional neural network to pre-train the original data set, and then perform further fine training based on the expanded face age database. Finally, the Sub-CNN of the four races is combined with the joint feature selection based on the group sparse algorithm to solve the age estimation problem based on the face image. The present invention obtains a human face age estimation model with more generalization ability, and can also greatly improve the performance of many age human face recognition systems, making up for the inadequacies of previous studies.

Description

technical field [0001] The invention relates to a method for estimating the age of a human face, in particular to a method for estimating the age of a human face based on collaborative selection of multi-ethnic characteristics based on GAN expansion. Background technique [0002] With the rapid development of related theories and applications of human-computer interaction, age information, as an important biological characteristic of human beings, has many application requirements in this field and has an important impact on the performance of face recognition systems. However, most of the research is based on existing data sets. Because there are too few samples of yellow, brown and other races in many existing large data sets abroad, the age recognition of yellow, brown and other race pictures is greatly limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a face age estimation method based on GAN extended ...
