Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0042] Explanation of technical terms:

[0043] Long Short-Term Memory (LSTM, Long Short-Term Memory) network is a time cyclic neural network, which is specially designed to solve the long-term dependence problem of ordinary RNN (cyclic neural network). Due to the unique design structure, LSTM is suitable for processing and predicting important events with very long intervals and delays in time series. The ingenuity of the LSTM network is that by adding input gates, forgetting gates and output gates, and designing the weight coefficients between connections, the LSTM network can accumulate long-term connections between distant nodes and achieve long-term memory for data.

[0044] Bi-LSTM (Bi Long Short-Term Memory) network, bi-directional long short-term memory neural net...

Abstract

The invention provides an age prediction method and device, and relates to the field of image recognition. According to the age prediction method, the age prediction result corresponding to the face image is output according to the face feature, the face dynamic change feature and the pre-trained age prediction model, so that the face feature of each face image in the face images collected at multiple moments is considered; and the face dynamic change features of the face images collected at multiple moments are also considered. Therefore, the accuracy of the predicted age information is higher.

Description

technical field [0001] The present application relates to the field of image recognition, in particular, to an age prediction method and device. Background technique [0002] Generally, in the field of image recognition, the age of the user corresponding to the face image can be predicted by extracting the image features of the face image and then analyzing the extracted image features. [0003] At present, the specific method of determining the age of the user corresponding to the face image through image recognition is: obtain the four partial images of the left eye, right eye, nose, and mouth of the face image, and extract the multi-scale local features of the four partial images respectively, And the multi-scale local features of the extracted four parts of the local image are connected in series to obtain the face fusion feature. Finally, predict the age of the user corresponding to the face image according to the face fusion feature. However, the accuracy of the user...
