Embodiment Construction

[0032] 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.

[0033] Such as figure 1 As shown, a non-invasive age estimation method based on skin texture information includes the following steps:

[0034] S1: acquiring skin surface images;

[0035] The texture of different parts of the human skin is quite different. Compared with the skin of other parts, the texture of the skin on the inner forearm is clearer, less affected by the external environment, less frequent muscle movement, and convenient for image collection. Therefore, this method selects the image of the skin in the middle part of the inner forearm as the processing object.

[0036] In the course of the research, the selected skin image samples came from 150 volunteers, ranging in age from 19 to 78 years old, with an average age of 43.2 years, and they were rand...

Abstract

The invention provides a noninvasive age estimation method based on skin texture information, which excavates skin surface texture information changing with age, aiming at providing a new, convenient and noninvasive age deduction method for medical workers. The method comprises: first noninvasively collecting the skin image of a forearm ventral side central section; preprocessing the collected skin image and extracting characteristics to obtain skin texture lines and a gray-level co-occurrence matrix; and finally calculating corresponding characteristic parameters, and utilizing a statistical method to analyze the correlation between the parameters and age to obtain an age deduction mathematical model. Statistical results show that the skin texture parameters in the method all have higher linear correlation with age; the age deduction mathematical model obtained through statistics analysis is used for testing 15 volunteers, and obtained age deduction errors are all within three years, which proves the effectiveness of the age estimation method; in addition, the age estimation method is extremely low in cost, and is hopeful to be used for medical age objective deduction.

Description

technical field [0001] The invention relates to the technical field of life sciences, in particular to a non-invasive age estimation method based on skin texture information. 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 infor...
