Problems solved by technology

[0004] However, the above-mentioned technical solution does not overcome the influence of the image edge. If the image edge, such as rough areas such as around the eyes and around the mouth, is counted as a skin area, the finally obtained dermabrasion coefficient will be higher than the actual value. The results tend to have a greater impact

Abstract

The invention provides a skin roughness adaptive skin exfoliating method and system and a client. The skin roughness adaptive skin exfoliating method comprises steps of obtaining an image to be processed, presetting one or more than one average characteristic vectors and an exfoliating coefficient corresponding to the preset average characteristic vector, extracting a characteristic vector of the image to be processed, successively comparing the characteristic vectors of the image to be processed with the preset average characteristic vector, obtaining corresponding similarity coefficients one by one, and obtaining an exfoliating coefficient of the image to be processed. Through extracting the characteristic vector of the image to be processed, the skin roughness adaptive skin exfoliating method and system and the client compare the characteristic vector of the image to be processed with the preset average characteristic vector to obtain a corresponding similarity coefficient, combine with the preset exfoliating coefficient to obtain the exfoliating coefficient of the image to be processed, dynamically regulate the exfoliating coefficient according to the skin quality of the processed image, can avoid detail loss of the image because of excessive exfoliating and perform accuracy exfoliating.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method, system and client for skin roughness self-adaptive microdermabrasion. Background technique [0002] Facial beautification is widely popular, and microdermabrasion is essential as a key core technology, and the intensity control of microdermabrasion determines the quality of the final effect. The current image processing software, such as photoshop, Meitu Xiuxiu, etc., are all controlled by fixed default parameters, which affect the user experience with manual adjustment. [0003] The patent document with application number 201310653333.X discloses a method and device for image processing. The image processing method includes: receiving an image to be processed; obtaining the first gray value of each pixel from the image; The first grayscale value of each pixel point is converted into a grayscale image in the face skin area in the image to be processed; according...
