Description
Technical Field
The invention belongs to the field of image analysis and processing, and particularly relates to a basin-shaped presentation method for skin white spots based on volume content of melanin.
Background
Currently, there are mainly the following means in the field of non-invasive quantitative detection of skin components, 1) image-based skin analysis. Because of the planar image analysis, the parameters that can be measured are mainly surface features, and quantitative skin composition data cannot be obtained. 2) The light with three wavelengths emitted by the multispectral instrument irradiates the surface of the skin, the receiver measures the light reflected by the skin, and the skin blackness and the heme content are measured according to the light quantity absorbed by the skin. The multispectral information is limited in quantity, skin component information with independent optical properties cannot be separated, and accurate quantification is difficult. 3) The measurement of the permittivity of the skin surface is relied upon to obtain a rough estimate of the moisture content. The correlation quantity is detected, and the index is an index and is not a real physical quantity. 4) In a volume reflection confocal microscope, a 830nm laser is adopted to observe the melanin at a cell level through the high refraction property of the melanin based on an optical confocal principle. The quantitative analysis of the quantitative melanin distribution pattern cannot be performed because the quantitative observation is limited and the target area is relatively small. 5) A skin spectrum detection system. In this way, the spectrum is used to perform visual comparison and observation of a certain wave band, and no information processing model is formed.
The use of hyperspectral images of the skin to calculate biological parameters related to the light absorption of the skin has been the area of intense research by the applicant and has been filed with various patent applications including: application number 201610181986.6, "a modeling method of human skin spectrum, a mathematical modeling method of a plurality of skin parameters with high fitting degree"; application number 201610182873.8, "a method for calculating 19 biological parameters related to light absorption of human skin using a mathematical model", etc. In particular, the method realizes the calculation of 19 biological parameters related to skin light absorption by using a hyperspectral image of skin for the first time, wherein the calculation of the volume content of eumelanin and pheomelanin in the epidermis layer of the skin is performed.
Skin white spots affect the beauty, and usually attract attention and take intervention measures, and quantitative evaluation of the change condition of the white spot area is required. At present, the main method for judging the progress of the white spots is visual observation or photo comparison, but the intrinsic cause of the white spots is skin melanin component loss from the skin mechanism, and the visual or photo of the white spots is surface information and mixed information which are inconsistent with the real distribution condition of melanin, so that the method is limited to rough qualitative observation, and the area of the white spots cannot be accurately calculated, and the effect of intervention measures can not be evaluated.
Therefore, the method has important effects on the accurate measurement, visual morphological expression, dynamic monitoring and the like of the melanin content in the skin, and the effects on the melanin content by taking intervention actions such as beautifying, whitening and the like.

Drawings

FIG. 2 is an illustration of the extraction and calculation of melanin content in skin white spots of a target area and the graphical presentation, the white spot area being "basin-like".
Detailed Description
The technical scheme of the invention is specifically described below with reference to the accompanying drawings.
In the present invention, "content" means a volume content.
The invention relates to a skin white spot basin-shaped presentation method based on melanin volume content, which comprises the following steps:
(1) Collecting hyperspectral images of skin of a target area;
(2) Extracting and calculating the melanin volume content of each pixel in the hyperspectral image by using a skin hyperspectral simulation algorithm to obtain distribution data of the melanin volume content of a target area;
(3) The data are subjected to color matching and then are presented as images, and the skin white spot area is in a basin shape.
In the invention, hyperspectral images of skin in a target area are acquired, and distribution data of melanin volume content in the target area are obtained by utilizing a skin hyperspectral simulation algorithm, wherein the simulation algorithm adopts application number 201610182873.8, and a method for calculating 19 biological parameters related to human skin light absorption by utilizing a mathematical model is adopted. The method realizes the calculation of 19 biological parameters related to skin light absorption by using the hyperspectral image of the skin for the first time, wherein the calculation of the volume content of eumelanin and pheomelanin in the skin epidermis layer is performed.
The skin white spot area in the present invention takes on a "basin" shape, with a specific meaning. The distribution data of the melanin volume content of the target area is subjected to color matching in a certain mode and is in a shape after being displayed in an image, and the distribution data is called as a basin shape for convenience of expression. The characteristics of high surrounding and low middle are presented morphologically; from the colors, an upper color system and a bottom color system are presented, and the intermediate transition zone is a gradient color, typically as shown in fig. 2.
The melanin volume content of each pixel in the step (2) is the sum of the excellent melanin and the brown melanin content of the pixel calculated by a skin hyperspectral simulation algorithm.
Wherein the melanin content color matching image expression in the step (3) is color matching in a way of gradually changing from dark red to dark blue, namely the higher the melanin content is, the more the dark red is presented; and on the contrary, the color is dark blue. The above-described color matching is a typical color matching method. But in practice this option is not the only option. Either color scheme will make it visually appear as a "basin" like feature.
The invention originally realizes an imaging presentation method for the volume content of melanin in the skin white spot area, and particularly the imaging presents a basin shape. The basin-shaped appearance can clearly and three-dimensionally observe the whole visual sense of the distribution form of the volume content of melanin in skin, and observe the detail changes of transition areas, basin areas and the like.
