Problems solved by technology

[0003] Although personalized cartoon animation has a good application prospect, so far almost all personalized cartoon animations are hand-created by animators. The output is low and the cost is high, which cannot meet the growing demand of consumers for personalized consumption.

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] see figure 1 , the face animation synthesis method of the embodiment of the present invention comprises the following steps:

[0036] Step 01: Obtain the frontal image of the human face to be synthesized with animation. In this embodiment, the frontal image of the human face is obtained by a digital camera.

[0037] Step 02, perform 3D face model estimation based on the face frontal image.

[0038] Specifically, first construct a training set containing m 3D face shape models {s 1 ,s 2 ,...,s m}, let the 3D model s j (1≤j≤m) and the feature point p on the face image t =(u t ,v t ) T (1≤t≤k, k is the number of feature points on the face image) the corresponding vertex is v tj . Find the optimal three-dimensional point by optimizing the following basic functions so that the two-dimensional coordinates of its vertices and p t closest.

Abstract

A method for synthesizing human face animation, comprising the steps of: obtaining a frontal image of a human face to be synthesized by animation; performing three-dimensional human face model estimation based on the frontal image of a human face; performing synthesis of a cartoon effect of a frontal human face based on facial feature analysis, Obtaining the synthetic figure of the cartoon comic effect of the frontal face; performing the synthesis of the cartoon effect of the multi-pose human face based on the estimation of the three-dimensional model of the human face and the synthetic figure of the cartoon comic effect of the positive face; synthesizing the cartoon effect of the multi-position human face of the synthesis Embed in the preset animation video material to get an animation video with a cartoon face effect. The method for synthesizing human face animation avoids the traditional manual creation of animation with a cartoon effect on the face, is simple and fast to implement, and can meet the different individualized needs of various users.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for synthesizing human face animation with a cartoon effect. Background technique [0002] With the vigorous development of multimedia carriers such as mobile phones and the Internet, the digital cartoon and animation industry has grown rapidly and has gradually become a mainstream cultural product in the information age. [0003] Although personalized cartoon animation has a good application prospect, so far almost all personalized cartoon animations are hand-created by animators. The output is low and the cost is high, which cannot meet the growing demand of consumers for personalized consumption. Contents of the invention [0004] In view of this, it is necessary to provide a fast and personalized face animation synthesis method. [0005] A method for synthesizing human face animation, comprising the steps of: [0006] Obtain the frontal image of the face to be syn...
