Problems solved by technology

The main reason is that the age discrimination of people is often inaccurate even through human eyes, so age discrimination is not a typical classification problem; Face images of age groups are a problem in themselves, and there are not many age databases as the basis for research
[0006] The existing age discrimination technology based on the anthropometric model can not distinguish the newborns from the elderly who have wrinkles on the face but have different forms, and can only distinguish the age through the wrinkles and forehead of the face. The face age is roughly divided into three categories: children, youth and old age, and it is impossible to complete fine age discrimination

Embodiment Construction

[0060] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] Shape and texture are effective features of human faces. Generally speaking, faces of different age groups have different shapes and textures, and faces of different age groups have similarities in some aspects. There are wrinkles on the faces of the children and the elderly. Therefore, it is necessary to analyze and process the faces according to different levels in order to effectively carry out age discrimination for face images.

[0062]The core idea of ​​the present invention is to design a multi-level age discrimination method for the differences in shape and texture of faces of different age groups, and the similarity of faces of different age groups in a certain aspect.

[0063] refer to figure 1 , which shows a f...

Abstract

The invention provides a method and a device for determining the age of a face image. The method comprises: performing rough estimation of the age of the image according to texture and shape characteristics; if the result of the rough estimation falls into an oldest age group or a youngest age group, finishing the operation; otherwise, performing detailed estimation on the effective face image according to face image characteristic library acquired from a specific age group sample, and determining the group to which the age of the face image belongs according to the result of the detailed estimation. The method and the device are used for improving the accuracy of image determination.

Description

technical field [0001] The invention relates to the field of face image processing, in particular to an age discrimination method and device for face images. Background technique [0002] Face recognition technology has been intensively studied in recent years due to its wide application prospects. But another technology related to facial recognition that has not received much attention is age change. [0003] When a person grows up from birth, with the growth of facial bones, the shape of the face becomes longer and larger, and the appearance also changes; while the process of aging from youth to old age, the skin gradually ages and wrinkles continue increase. Therefore, if the age can be accurately judged according to the face image, it will help to correctly identify the identity of the person. [0004] In addition, age discrimination has many applications in the field of human-computer interaction. For example, web browsers can decide whether to allow users to view ce...
