Problems solved by technology

[0003] The existing face-lifting technology is either not highly automated and requires the user to manually specify the face-lifting position, and can only perform local face-lifting on the specified part, which is likely to cause uneven face-lifting effects and facial features deformation; or the pixel changes in the filled area after face-lifting large, making the beautified image abrupt; or the complexity of the face-lifting algorithm is high, and it is difficult to implement the application

Abstract

The invention discloses an image processing method and apparatus for realizing a face thinning special effect, and an electronic device. The method comprises the steps of detecting multiple key pointsof a human face image; establishing a coordinate system, and determining coordinates of the multiple key points and pixel points; according to the coordinates, determining relative position relationships between the to-be-processed pixel points and the multiple key points, and determining compression coefficients of the coordinates of the to-be-processed pixel points; performing conversion on thecoordinates of the to-be-processed pixel points to obtain new coordinates after conversion, and determining the target pixel points corresponding to the new coordinates; and assigning pixel values ofthe target pixel points to the to-be-processed pixel points. By utilizing the scheme, face thinning can be realized only according to the relative position relationships between the to-be-processed pixel points and the multiple key points; an algorithm is simple and easy to implement; face thinning processing degrees of different to-be-processed pixel points are different, so that a human face image subjected to face thinning processing is more aesthetic; and in addition, the whole human face image is subjected to full-automatic face thinning, so that the face thinning effect is uniform and natural.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image processing method, device and computing device for realizing a face-thinning special effect. Background technique [0002] With the development of computer image processing technology, image beautification has become more and more convenient and popular. Among them, since in terms of modern aesthetic taste, a thinner face is generally considered to have a better aesthetic feeling, therefore, the face-slimming technology in image beautification has received widespread attention and favor from people. [0003] The existing face-lifting technology is either not highly automated and requires the user to manually specify the face-lifting position, and can only perform local face-lifting on the specified part, which is likely to cause uneven face-lifting effects and facial features deformation; or the pixel changes in the filled area after face-lifting large, making ...
