Abstract

The present invention provides an age estimation method and device, the method comprising: performing gender training on a gender model according to face image samples, so that the gender model converges, wherein the gender model includes at least two convolutional layers; Perform age training on the age model according to the face image samples and the converged weights of the at least two convolutional layers, so that the age model converges, wherein the age model includes the at least two convolutional layers ; Estimate the age of the input face image according to the converged age model. The present invention can eliminate the problem of inaccurate age estimation caused by gender differences in face images, thereby improving the accuracy of age estimation.

Description

technical field [0001] The present invention relates to the technical field of computer vision, and in particular, to an age estimation method and device. Background technique [0002] At present, as the age of face images is more and more widely used in the fields of Internet user portrait, accurate advertisement push, image or video recommendation, etc., the demand for age estimation of face images is also increasing. [0003] At present, the age estimation methods of face images mainly include traditional machine learning methods. Specifically, artificial features are first designed and defined, such as hog (Histogram of Oriented Gradient, directional gradient histogram), sift (Scale-Invariant Feature Taransform, Then, a dimensionality reduction method is used to extract effective features useful for age estimation, and finally a regression model is used to detect the age of the face image. [0004] However, the features learned by traditional machine learning methods ar...
