Abstract

The invention discloses a method for reducing nose wings based on a human face grid. The method includes: collecting a human face image to be processed; performing face recognition on the human face image to obtain the feature points of the face area, wherein the The feature points of the face region include at least the feature points of the corners of the mouth, the alar region of the nose and the peripheral contour of the cheek; interpolation is performed according to the distance ratio between the feature points of the alar region of the nose and the peripheral contour and the corner of the mouth, and the supplementary feature points of the alar region of the nose are obtained , the supplementary feature points and the original feature points of the alar region together constitute the point set of the alar region; according to the point set of the alar region, it is triangulated to obtain a plurality of triangular meshes; from the multiple Select the vertices located on the nose and distributed on both sides of the bridge of the nose from the vertices of the three triangular meshes; adjust the position of the selected mesh vertices to obtain a transformed new triangular mesh. The invention discloses a nose wing reduction device and computing equipment based on human face grid.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a face grid-based method, device and computing device for reducing nose wings. Background technique [0002] With the development of the field of image processing, the beauty of face images has become an increasingly important beautification function. More and more users are loyal to using image processing software to adjust their facial features, so as to achieve beautification or funny effects. However, limited by the user's camera environment and the difference in camera angles, in many cases the pictures taken by the user do not really show their best side. Therefore, users can use image beauty applications to adjust the facial features of unsatisfactory pictures after shooting. [0003] In the existing techniques for modifying facial features, users generally use the liquefaction function of PhotoShop to manually adjust the picture. In this case, it usually requires...
