specific Embodiment approach

[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 beautifying method and a face beautifying device in an image. The method comprises the following steps of detecting the face region of a target image; determining a peripheral region surrounding the face region and the face region as to-be-beautified regions; subjecting to-be-beautified regions to face-beautifying treatment, and generating a first face-beautified image corresponding to the target image, wherein the first face-beautified image contains a face-beautified face region corresponding to the face region, a face-beautified peripheral region correspondingto the peripheral region and a background region corresponding to the to-be-beautified regions; subjecting the face-beautified peripheral region in the first face-beautified image to smooth treatmentso as to generate a second face-beautified image corresponding to the target image, wherein the second face-beautified image contains the face-beautified face region, a smoothed peripheral region anda smoothed background region corresponding to the face-beautified peripheral region; outputting the second face-beautified image. In this way, the distortion technical problem of a face-beautified image can be solved.

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...
