A 3D face animation manufacturing method based on region segmentation and segmented learning

Abstract

The invention discloses a 3D face cartoon animation method based on region segmentation and subsection learning. The invention has the following steps of: first obtaining sparse 3D movement capturing data and 3D face surface mesh; next calibrating the control point corresponding to the movement capturing data on the 3D face gridding; separating the rigidity and non-rigidity movement in the movement capturing data, and aligning the movement capturing data and the face model in static state; clustering the acmes of the face model based on the cosine distance of the displacement vector of the movement capturing data and the manifold distance of the 3D face gridding acmes; training the segmented surface patch to be subsection radial basis function; and fusing the border movement via the advanced Voronoi-Cell arithmetic. The invention can execute the automatic regional segmentation to a single face model, and model the face non-rigidity movement via subsection radial basis function to form the face cartoon with the third dimension.

Description

technical field [0001] The invention relates to a method for area division of a three-dimensional human face grid, relates to a method for facial expression movement and deformation of a three-dimensional human face grid, and belongs to the technical field of computer three-dimensional animation. Background technique [0002] The earliest work on 3D facial animation technology began in 1972. Subsequent scholars have done a lot of work in order to generate realistic and vivid 3D facial animation. However, due to the complex anatomical structure of the human face, the subtle non-rigid movements are difficult to model mathematically, and at the same time, people's sensitivity to the appearance of the human face makes this topic very difficult. At present, some progress has been made in the work of realistic 3D facial animation, which can basically be divided into the following categories: [0003] Interpolation-based methods: The earliest facial animations were based on inter...
