Embodiment 3

[0103] Figure 5 It is a schematic structural diagram of an expression animation generating device according to an exemplary embodiment. refer to Figure 5 , the device includes a collection module 501 , an extraction module 502 and a generation module 503 .

[0104] Acquisition module 501, for collecting the deformation animation of face image;

[0105] The extraction module 502 is used to extract the feature points from the face image included in the deformation animation to obtain the feature point animation of the face;

[0106]The generation module 503 is configured to generate an expression animation based on the facial feature point animation and a target expression template, where the target expression template is a two-dimensional or three-dimensional expression model with multiple control points.

[0107] Optionally, see Figure 6 , the generation module 503 includes:

[0108] The moving unit 5031 is used to move a plurality of control points included in the tar...

Abstract

The invention discloses a method and a device for generating an expression animation, belonging to the Internet field. The method disclosed by the invention comprises steps of collecting a deformation animation of a face image, performing characteristic point extraction on the face image included in the deformation animation to obtain a human face characteristic animation, and generating an expression animation based on the human face characteristic point animation and a target expression template, wherein the target expression template is a 2D or 3D expression model having a plurality of control points. The invention obtains the human face characteristic point animation through collecting human face image animation and extracting the human face characteristic points, determines the target expression template to generate the expression animation, reduces the difficulty and cost for generating the expression animation, and enables the user can generate some personalized expression animation on their own.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and device for generating facial expression animation. Background technique [0002] With the rapid development of the Internet, more and more instant messaging tools have emerged. When users use these instant messaging tools to communicate, they often use the emoticons that come with these instant messaging tools. Most of these emoticons are created by designer to design. And when users want to use some personalized emoticons, they often need to collect them online, or collect some favorite emoticons in the process of communicating with other users. That is to say, for ordinary users, the threshold for generating emoticon animation is relatively high, and the cost is also relatively high. Therefore, there is an urgent need for a low-threshold, low-cost expression animation generation method. Contents of the invention [0003] In order to solve the problems in the prior ...
