IMAGE ADJUSTMENT METHOD, DEVICE, STORAGE MEDIUM, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/012596
Kind Code:
A1
Abstract:
Provided are an image adjustment method, a device, a storage medium, and an apparatus. The method comprises: acquiring a first image, performing face detection on the first image, and obtaining a face feature point set; selecting several face feature points from the face feature point set as face deformation constraint points; performing calculation according to the coordinates of the face deformation constraint points to obtain face deformation constraint quantities; adjusting, according to the face deformation constraint quantities, coordinates of face outline feature points in the face feature point set, and obtaining a second image; performing an affine transformation on pixels in the first image, and obtaining transformation coordinates of the pixels in the second image; and filling a pixel value in the second image according to the transformation coordinates, and obtaining a third image. The invention adjusts the coordinates of the face outline feature points in the face feature point set according to the face deformation constraint quantities determined from the face deformation constraint points, thereby preventing a face from having a pointed jawline or the cheeks losing curvature during an image processing process of the face, and preventing background distortion and deformation.
