Embodiment 1

[0053] Step 1, digital image acquisition of the tester's human facial skin;

[0054] Using facial image acquisition equipment (Yiheng brand, the latest high-definition 5-megapixel skin detector model EH-900U) to collect the skin quality images of the four parts of the tester's face, forehead, left eye corner, left cheek and chin, as shown in the attached figure 2 shown.

[0055] Step 2. Obtain the normalized value of the tester's gloss calculation value;

[0056] Use the algorithm based on single-scale Retinex (SSR) to process the digital image of human facial skin to obtain the reflection image, and obtain the skin glossiness calculation value according to the average value of the reflection image pixels, and use the glossiness data in the existing tester sample database to calculate the glossiness Values ​​are normalized to get the normalized value of the glossiness calculation. The normalized value of the glossiness calculation is used as the input value of the built mod...

Abstract

The invention discloses a method for calculating human facial skin moisture and elasticity indexes based on digital image processing technology, and belongs to the field of cosmetic science and technology. In the present invention, on the basis of obtaining the calculated value of skin glossiness by digital image processing technology, the conversion model of the normalized value of the measured value of skin glossiness and the normalized value of moisture, the normalized value of the measured value of glossiness and the normalized value of elasticity are constructed. The integrated value conversion model calculates the calculated values ​​of skin moisture and elasticity indexes, thus providing an effective way to simplify the index acquisition method and improve the operability of skin measurement, so as to realize the multi-index comprehensive evaluation of human facial skin quality. The invention utilizes the digital image processing technology, simplifies the index acquisition mode and calculation model, improves the operability of skin measurement, and improves the accuracy and reliability of the calculation of skin moisture and elasticity index values.

Description

technical field [0001] The invention relates to a method for calculating human facial skin moisture and elasticity indexes based on digital image processing technology, and belongs to the field of cosmetic science and technology. Background technique [0002] With the continuous improvement of material living standards, people pay more and more attention to the quality of their own skin. As the natural barrier of the human body, the skin has the functions of protection, sensation, absorption, secretion, excretion, temperature regulation and immunity. It is also one of the important aesthetic standards. Therefore, a simple and effective calculation method of skin state parameters has important scientific value and practical significance. [0003] At present, many scholars at home and abroad are devoted to the research of skin quality measurement and evaluation. The key physiological indicators of the skin include moisture, elasticity, etc. Evaluation of these indicators is h...
