Abstract

Aspects of the embodiments of the present invention relate to a face image shaping method and device. The face image shaping method comprises the steps of obtaining a face image; obtaining key pointsof the face by detecting the face image, wherein the key points comprise face center line key points; generating a first face triangularization grid based on the key points; obtaining a central pointneeding to move in the key points and a movement vector of the central point, and obtaining a changed second face triangularization grid based on the central point and the movement vector; and according to the first face triangularization grid and the second face triangularization grid, rendering the face image to obtain a shaped image. According to the embodiment of the invention, the large-angleside face can be shaped, and the appearance value is effectively improved.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of image processing, and more specifically, relate to a face image shaping method and device. Background technique [0002] Face beautification is a common function in taking pictures or retouching software. The traditional beauty algorithm can realize simple big eyes and thin face, while the advanced beauty algorithm can fine-tune the facial features, including nose augmentation, chin sharpening, eyebrow trimming and other functions. The limitation of these beautification algorithms is that they cannot perform plastic surgery on large-angle side faces. Usually, when the face is turned to a certain angle, many of the effects of frontal face shaping are turned off. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, embodiments of the present invention provide a face image shaping method and device. [0004] In the first aspect, an emb...
