Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] The first embodiment of the present invention provides an age estimation method. Based on the generative adversarial network, a face age database with a balanced age distribution is obtained. On the basis of the obtained face age database, transfer learning is used to train the constructed face age database The deep convolutional neural network with residual structure makes the network have shorter training time, faster convergence speed and more accurate weight parameters, so as to obtain highly prepared age estimation results. Such as figure 1 It is a flow chart of the age estimation method of the embodiment of the present invention, such as figure 1 shown, including the following steps:

Abstract

The invention discloses an age estimation method and device. The method comprises the steps of inputting a pre-processed to-be-tested human face image into a trained deep convolutional neural network,and acquiring an age estimation result of the to-be-tested human face image. The age estimation method and device have the beneficial effect of acquiring highly accurate age estimation result.

Description

technical field [0001] The present invention relates to the field of computer vision, and more specifically, to an age estimation method and device. Background technique [0002] Face is one of the most important biological characteristics of human beings, which plays a major role in identifying identity and conveying emotions. In recent years, research based on face images, including face detection, identity authentication, face attributes (gender, age, expression, race) and other recognition issues has become a research hotspot in the fields of computer vision and human-computer interaction. Among them, age estimation technology has many application requirements in the field of human-computer interaction, and it is of great significance to use computers to realize automatic face age estimation. For example, in terms of security monitoring, the age recognition system can be used to automatically identify the age of a person to achieve network security or to control the sec...
