Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] According to the traditional Peking Opera masks, the present invention uses Bezier curves to fit the contours of each pattern to model the facial makeup model; uses the AdaBoost algorithm based on Haar features to improve the AAM model, thereby identifying the faces that have detected motion and their feature points; Some deformation t...

Abstract

The invention discloses a facial projection method based on facial features, which establishes a database of facial makeup patterns; acquires video frames containing human faces, and performs grayscale processing; acquires all Haar features of each position on the grayscale image, and calculates Its eigenvalues; use the Adaboost algorithm to train the eigenvalues ​​to obtain the optimal feature points for each position; add the feature points to the active appearance model to calculate the nose tip coordinates of the face, the face plane deflection angle and the side depth deflection angle , to establish a face model; select the desired facial makeup pattern and select the facial makeup pattern control points, fit the facial makeup pattern to obtain a fitting curve; deform and combine the fitting curve to obtain a facial makeup model; according to the nose tip coordinates and face plane deflection Angle and side depth deflection angle to adjust the projection angle; project the face model onto the face model. The method disclosed by the invention is flexible, simple and quick, and can accurately project facial makeup onto human faces in real time.

Description

technical field [0001] The invention relates to the field of face recognition and special-shaped projection, in particular to a face projection method based on facial features. Background technique [0002] Facebook is attached to the face, so the research on the application of Facebook must be inseparable from face detection and tracking. Projecting the well-integrated face mask obtained after processing on the moving face is a new application of cultural inheritance and a new category of special-shaped projection. Alien projection is to project the projection on the heterohedron. In this paper, the face is regarded as the heterohedron. Generally speaking, it is to project and cover the tracked face. [0003] In 2015, a Japanese artist invented the facial holographic projection technology (Face Hacking). Face Hacking integrates three functions: 3D scanning, real-time face tracking and projection mapping. It first scans and locates the model's facial contour, and then use...
