Skin image information processing-based age testing method

Abstract

The invention provides a skin image information processing-based age testing method. According to the invention, based on the mining of age-related changing texture information of skin surface, a novel, simple and noninvasive age estimation method is provided for medical workers. According to the skin image information processing-based age testing method, a skin image of the middle segment of the ventral side of a forearm is acquired in a noninvasive manner; preprocessing and feature extraction are performed on the acquired skin image, so that relevant parameters of skin grooves and skin ridges are obtained; and the correlation between the parameters and the age is analyzed by using a statistical method, so that the mathematical model of age inference can be obtained. As indicated by statistical results, the skin texture parameters obtained through adopting the method all have high linear correlation with the edge; and when the edge inference model which is obtained through statistical analysis is tested, high accuracy can be obtained. Thus, the effectiveness of the method in age inference can be proved, and cost required by the method is low, and therefore, the method can be prospectively used for objective inference of medical age.

Description

technical field [0001] The invention relates to the technical field of life sciences, in particular to an age testing method based on skin image information processing. Background technique [0002] Age is a natural marker with a biological basis. Inferring the age of individuals is a work often encountered in medical research and criminal investigation, including age inference for immigrants, anonymous persons, athletes and suspects, so as to provide reliable clues and science for medical research, investigation and handling of civil cases, etc. evidence. The current clinical age estimation methods for adults are mainly based on bone changes and the degree of tooth wear, requiring physicians to observe and evaluate with the naked eye according to scoring standards, and its accuracy is easily affected by physicians' supervisory factors. [0003] In addition to bone changes and tooth wear, there are many tissues and organs in the human body that also express age information...

Problems solved by technology

[0004] However, in recent years, most researchers have used skin silicone lamination methods to measure skin parameters. Such methods are more complicated and prone to errors

Some scholars also study skin aging by taking pictures of the skin on the back of the hand to obtain images, but the calculation of parameters in this method is manual calculation, which is time-consuming and laborious, and the intelligence of the algorithm is relatively poor
