[0085] Rectangular width W of the rectangular face area 0 The calculation result is: W 0 =x 1 -x 2 , the rectangular height H of the rectangular face area 0 The calculation result is: H 0 =y 2 -y 1 . The preset zoom-in parameter is a, then the width of the rectangle of the area to be beautified is W 1 The calculation result is as follows: W 1 =W 0 Хa. Then the rectangle height H of the beautification area is 0 The calculation result is: H 1 =H 0 Хa. Specifically, the abscissa x of the coordinates of the upper left corner in the diagonal coordinates of the area to be beautified is calculated by the following formula 1 'for: x 1 '=x 1 -(W 1 -W 0 ) / 2; Calculate the abscissa x of the coordinates of the lower right corner in the diagonal coordinates of the area to be beautified by the following formula 2 'for: x 2 '=x 2 +(W 1 -W 0 ) / 2; Calculate the vertical coordinate y of the upper left corner coordinates in the diagonal coordinates of the area to be beauti...

Abstract

The invention discloses a face beautification method and device in an image, comprising: detecting the face area in the target image; determining the peripheral area surrounding the face area and the face area as the area to be beautified; Beautifying the area to generate the first image after beautifying corresponding to the target image, the image after the first beautifying includes the face area after beautifying corresponding to the face area, the peripheral area after beautifying corresponding to the peripheral area, and Relative to the background area of ​​the area to be beautified; by smoothing the peripheral area after the beautification in the first image after beautification, to generate a second image after beautification corresponding to the target image, in the second image after beautification Including the face area after beautification, the smooth peripheral area and the background area corresponding to the peripheral area after beautification; output the second image after beautification, thus the present invention solves the technical problem of image distortion after beautification.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for beautifying human faces in images. 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 to adjust the color of the image to make people's skin tone look whiter and more beautiful, including adjusting colo...
