Abstract

Aspects of the embodiments of the present invention relate to methods and devices for face image rhinoplasty. The face image rhinoplasty method includes: obtaining a face image; based on the face image, obtaining key points of the face, wherein the key points of the face include key points of the midline of the face, key points of the outline of the nose, and key points of the tip of the left eyebrow , the key point of the right eyebrow tip, the upper side point of the nose bridge, and the lower side point of the nose tip; based on the key points of the face, generate the first nose triangle mesh; based on the first nose triangle mesh, obtain the first nose tip key point ; Obtain the movement vector of the first nose tip key point, based on the upper side point of the nose bridge, the lower side point of the nose tip, the first nose tip key point and the movement vector, obtain the changed second nose triangulation mesh; according to the first nose triangle and the second nose triangulation mesh to render the face image to obtain the plastic image. Through the embodiment of the present invention, rhinoplasty can be performed on the nose at any face angle.

Description

technical field [0001] The present invention generally relates to the field of image processing, and more specifically, relates to a method and device for nose shaping of human face images. Background technique [0002] Digital face shaping is a core function of current photo or image editing software. Traditional plastic surgery algorithms can usually achieve big eyes, thin face, thin nose, and chin reduction. Compared with the traditional face-lifting with big eyes, rhinoplasty is relatively difficult because it needs to obtain more accurate three-dimensional information of the face. At present, the limitation of the rhinoplasty algorithm is that it cannot perform rhinoplasty on the nose facing the face at any angle. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, embodiments of the present invention provide a face image nose shaping method and device. [0004] In the first aspect, an embodiment of the presen...
