Problems solved by technology

[0003] The current portrait beautification technology usually performs an overall operation on the entire image. Although the portrait beautification effect is up to standard, the calculation is very large, takes up a lot of computing resources, and the processing speed is slow; moreover, the background is not considered when beautifying the partial area of ​​the face. Sustained, the background at the edge of the region will appear noticeably deformed

Abstract

The invention relates to an image adjustment method and device and computer equipment, and the method comprises the following steps: carrying out the face detection of an input image, and obtaining aface feature point set; performing triangulation on the input image according to the face feature point set to obtain a plurality of original triangular images about the input image; performing coordinate adjustment on part of face feature points of the face feature point set to obtain a transition image; performing triangulation on the transition image according to the human face feature point set after coordinate adjustment to obtain a plurality of deformed triangular images about the transition image; judging whether the vertex coordinates of the corresponding original triangular image andthe deformed triangular image are the same or not; and if not, carrying out affine transformation on the pixel points in the original triangular image to obtain transformation coordinates of the pixelpoints in the deformed triangular image. The method has the advantages of local deformation and small calculation amount, and has a good maintaining effect on a non-deformation area and an image background.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image adjustment method, device and computer equipment. Background technique [0002] With the development and promotion of portrait beautification technology, users are no longer satisfied with the basic portrait beautification technology, and users are more and more interested in face deformation technology. The most typical application functions in portrait beautification technology are portrait big eyes and thin face, portrait big head and other local deformation functions. [0003] The current portrait beautification technology usually performs an overall operation on the entire image. Although the portrait beautification effect is up to standard, the calculation is very large, takes up a lot of computing resources, and the processing speed is slow; moreover, the background is not considered when beautifying the partial area of ​​the face. Maintained, the backgr...
