The application relates to a contour size rapid analysis method based on a surface skinning spot hole point cloud, which comprises the following steps: S1, performing voxel filtering on the scanned original point cloud P0 according to the installation angle of a laser sensor to obtain a point cloud P0 ＇ , then performing coordinate transformation and compensation of three directions of a laser sensor coordinate system X axis, Y axis and Z axis to obtain a transformed point cloud P1; S2, performing segmentation on the point cloud P1, and segmenting out effective data point cloud P2 and invalid data point cloud P3 by setting a default value; S3, adopting maximum outer circle fitting to extract a bottom hole center c and a bottom hole radius r for the invalid data point cloud P3; and S4, performing dimension reduction processing on the effective data point cloud P2 to obtain a point cloud P4 and the like. According to the structural features of the spot hole, the three-dimensional point cloud is segmented and dimensionally reduced, and the effect of fast, accurate and multi-parameter one-time measurement extraction is achieved, the traditional detection time is shortened from several minutes to 1.5 seconds or below, and the detection precision and stability are greatly improved.

Topical compositions for skin application comprising as active ingredient a) a fluid extract from branches and / or twigs of Vitis Vinifera L. b) a fluid extract from the bark of Abies alba Mill. c) a fluid extract from the bark of Pinus sylvestris L. in combination with suitable excipients and / or diluents. in which each of said fluid extracts includes or consists of the extraction product dissolved in the same solvent mixture consisting of water and 1,3 propanediol from which said product was extracted. Such topical compositions can be used in the cosmetic field for the treatment and prevention of the formation of skin spots.

A protein-peptide carrier particle structure in natural whole food form that can be used to improve skin lightening and radiance, as well as to reduce skin spots, comprising a layered carrier (01) consisting of a core (10) and a protective layer (20), wherein the core (10) is located inside the carrier (01) and the protective layer (20) is provided outside the core (10) to prevent the external environment from influencing the activity of the core (10), and thus to improve the storage stability of the carrier (01) and its absorption rate by the human body; wherein the core (10) comprises a 3D composite structure in natural whole food form that contains glutamic acid and glutathione in combination with protein-peptide carriers.

The present invention provides a fish collagen peptide with skin-lightening and freckle-removing effects, as well as a preparation method and application thereof, and belongs to the technical field of protein peptides. The present invention uses fish skin and / or fish scales as raw materials, and then performs heat treatment, homogenization treatment, enzymatic hydrolysis treatment and enzyme inactivation purification in sequence after degreasing and deodorizing treatment to obtain fish collagen peptide. In the fish collagen peptide prepared by the present invention, polypeptides of 189~3000Da account for more than 90%, and the protein content is as high as more than 99.23%. Experiments show that the fish collagen peptide can effectively reduce the proportion of skin spots on the subjects, and at the same time increase the L value and ITA value of the subjects' skin. It can be seen that the fish collagen peptide prepared by the present invention has good skin-lightening and freckle-removing effects, and provides a new way to prepare related products.

The invention discloses a skin image spot identification and quantitative evaluation method based on an RGB color space, and the method comprises the steps: calculating the number of spots, the average area, the proportion, the depth, the obvious degree and other attribute values of a skin image according to the pixel color value information of the RGB color space of the skin image; firstly, skin image spots are recognized, then multiple attribute values of the recognized spots are quantitatively calculated, and evaluation of skin spot features is achieved. The method is high in spot recognition and quantitative evaluation accuracy and speed, and has good market application prospects and value.
