Beautification method and system for adaptive lighting

Abstract

The invention discloses a method and system for beautifying skin with adaptive lighting, wherein the method includes the steps of: collecting live images through a camera; converting the original RGB data of the live images into YCbCr data, and finding out the skin color area in the YCbCr data; The noise in the live image is removed or blurred, and the denoised RGB image data F is obtained; the average brightness L of the skin color area is calculated according to the Y value in the YCbCr space of the pixels in the skin color area: according to the average brightness L of the skin color area, adjust the The beautification parameters of the noisy RGB image include brightness G, contrast J and saturation H; according to the adjusted beautification parameters, the skin color area is beautified to obtain the final beautification image. The invention detects the light intensity in the current environment through the average brightness of the skin color area, then dynamically adjusts the beautification parameters, and then adjusts the skin color area according to the beautification parameters, so that the beautification effect can better adapt to the light environment.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an adaptive lighting beautification method and system. Background technique [0002] Beautification is one of the most common functions in live broadcast products. The main products of Meitu, which is listed in Hong Kong, are beautification cameras and Meipai. Some media joked that it will impact the cosmetics industry. You can live broadcast confidently without makeup, and beauty allows users to take better pictures of themselves. The main principle of beautification is to achieve the effect of overall beautification through dermabrasion and whitening. The technical term of microdermabrasion is denoising, that is, removing or blurring the noise in the image. Common denoising algorithms include mean blur, Gaussian blur, and median filter. Whitening is actually adjusting the color of the image to make people's skin tone look whiter and more beautiful, including adjusting ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a parameter that can automatically adjust the beautification image according to the light intensity of the current scene in the beautification process, aiming at the defect that the beautification image cannot be automatically adjusted according to the light intensity of the current environment in the prior art, Beautification method and system capable of adapting illumination to make beautification effect not affected by intensity of light
