Problems solved by technology

However, there are still some deficiencies in the current open source datasets.
Taking the face data set as an example, on the one hand, there is a problem of limited overall samples, on the other hand, for a single face sample, it contains very limited feature attributes, and at the same time, the collection, organization, and labeling of the data set is a very time-consuming process. With the process of energy, it is very difficult to include a series of continuously changing feature attributes of all individual face samples in a large-scale data set
Therefore, these problems existing in the current face datasets limit the promotion of face recognition based on supervised learning methods in more application scenarios to a certain extent.

Embodiment Construction

[0091] see figure 1 , figure 2 , a face recognition method based on dual data enhancement, comprising the following steps:

[0092] S1. Select the appropriate data set

[0093] After comparison, in the present invention, the open source face data set of the Chinese University of Hong Kong - CelebA is selected as the data source for model training. This data set contains about 200,000 celebrity face images and more than 40 kinds of face feature labels, which lays a data foundation for generating corresponding continuously changing features in the present invention.

[0094] S2, data set preprocessing

[0095] The original size of the image in the CelebA dataset is 178×218, which will bring a large computational burden to the later training, so we crop it to 32×32. At the same time, they are normalized, and the pixel values ​​​​of the image are unified to [-1,1].

[0096] S3, the first layer of data enhancement

[0097] Build the generation confrontation network model (In...

Abstract

The invention discloses a human face recognition method based on dual data enhancement. A human face data set obtained through the dual data enhancement improves the accuracy of human face recognition. The method comprises the steps that S1, the data set is selected; S2, the data set is preprocessed; S3, primary data enhancement is performed: a generative adversarial network model based on information maximization is built, and training is completed; S4, secondary data enhancement is performed: human face samples generated in the step S3 are subjected to translation, rotation, turnover and zoom processing; and S5, human face classification is performed: the human face samples generated in the step S4 are trained and recognized by selecting a convolutional neural network model.

Description

technical field [0001] The invention belongs to the field of machine learning, in particular to a face recognition method based on double data enhancement. Background technique [0002] Supervised learning is a commonly used method in the field of machine learning. It refers to taking the data in a large-scale data set and the corresponding labels as the input of a certain mathematical model, and then training the model to learn the known data. Features, so as to process the unknown data. According to the definition of supervised learning, the data set is one of the key links to determine the performance of the final model. With the continuous development of deep learning technology and the emergence of open source datasets in different fields, supervised learning methods have been more widely used. However, there are still some deficiencies in the current open source datasets. Taking the face data set as an example, on the one hand, there is a problem of limited overall ...
