Abstract

The invention provides an age testing method based on skin image information processing, and attempts to provide medical workers with a new simple and non-invasive age estimation method by mining the texture information of the skin surface that changes with age. Firstly, the skin image of the ventral middle part of the forearm was collected non-invasively, and then the collected skin image was preprocessed and feature extracted to obtain the relevant parameters of the skin groove and skin crest, and the correlation between these parameters and age was analyzed by statistical methods. A mathematical model for inferring age. The statistical results show that the skin texture parameters in this method have a high linear correlation with age, and the age inference model obtained by statistical analysis can be tested to obtain a high accuracy rate, which proves the validity of the method in this paper to infer age , and due to its low cost, it is expected to be 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...
