Abstract

Aspects of the embodiments of the present invention relate to a face image nose shaping method and device. The face image nose shaping method comprises the steps of obtaining a face image; obtaining face key points of the face based on the face image, the face key points comprising a face center line key point, a nose contour key point, a left eyebrow tip key point, a right eyebrow tip key point,a nose bridge upper side point and a nose tip lower side point; generating a first nose triangularization grid based on the face key points; obtaining a first nose tip key point based on the first nose triangularization grid; obtaining a movement vector of the first nose tip key point, and obtaining a changed second nose triangulation grid based on the nose bridge upper side point, the nose tip lower side point, the first nose tip key point and the movement vector; and according to the first nose triangularization grid and the second nose triangularization grid, rendering the face image to obtain a shaped image. According to the embodiment of the invention, nose humping can be carried out 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...
