Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0019] Such as figure 1 As shown, it is the workflow of the identification and evaluation method of the intelligent face health degree, including the following steps:

[0020] Step 10 Image acquisition stage: collect face images for detecting acne and pigmentation, and assessing the health of the face;

[0021] Step 20 acne and spot detection stage: convert the face image from the RGB color gamut to the HSV color gamut, and detect skin acne through the binary image of the maximum brightness value image; use the face image through the ISODATA clustering algorithm to iteratively calculate Segment the threshold of the color spot lesion area and the skin area, obtain the edge contour of the skin color spot on the face and detect the skin color spot; ...

Abstract

The invention discloses an intelligent face health degree identification and evaluation method. The method comprises: an image acquisition stage: collecting a face image for detecting acnes and colorspots and assessing the health degree of the face; and an acne and color spot detection stage: converting the face image into an HSV color gamut from an RGB color gamut, and detecting acne through a binary image of the maximum brightness value image, iteratively calculating the threshold values of the segmented color spot lesion area and the skin area of the face image through an ISODATA clustering algorithm to obtain the edge contour of the face color spot and detect the color spot; quantitative measurement of acne and color spots: using the ROI to select acne in a framing manner, calculatingthe number of acnes, measuring color indexes of a color spot area and color indexes of color spots, and divides the color indexes into a serious degree, a common degree and a slight degree through the color spot area and the color depth; face health degree assessment: calculating the face acne score according to the acne number and the distribution condition, calculating the face color spot scoreaccording to the color spot number, the degree and the distribution condition, and comprehensively obtaining the face health degree score. According to the method, the health degree of the human faceis comprehensively judged through the two indexes of acne and color spots, the skin defects of the human face are rapidly and accurately detected, and quantitative indexes are provided.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image processing method for identifying and evaluating the health degree of human faces. Background technique [0002] With the continuous development of the beauty and skin care industry, people are paying more attention to skin quality. How to detect the defects of human face skin and quantify skin indicators has become a key technology. At present, the evaluation of the state of human face and skin in China mostly adopts the method judged by professional doctors, which is highly subjective, lacks objective analysis, and also lacks unified quantitative indicators, and is limited by medical resources and other factors, so it cannot be quickly and accurately Provide an appropriate diagnosis. In view of the above problems, it is necessary to design a method that can quickly and accurately detect human facial skin defects and provide quantitative indicators. [0003] Among the ...
