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

Embodiment Construction

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0036] Such as Figure 1-Figure 3 Shown, a kind of age testing method based on skin image information processing, comprises the following steps:

[0037] S1: The image of the skin surface is obtained through a digital microscope, and the lens of the digital microscope is fitted with a transparent base with a polarizer;

[0038] The skin texture structure is greatly affected by the external environment, and its structure is complex. Different body parts have different characteristics. For example, facial features have been used as age detection, and its shortcomings cannot be ignored. One is that the face is easily exposed to sunlight. The skin is greatly affected by the outside world; the second is that facial expressions are rich, and muscle movements vary greatly...

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...
