Abstract

The embodiment of the present application discloses a method and a device for generating virtual animation emoticons. The method for generating virtual animated expressions includes: obtaining the current frame of the human face video; obtaining the first weight coefficient and the emotional expression label of the facial expression grid corresponding to each basic expression base grid of the current frame; based on the emotional expression label, Determine the second weight coefficient of each emotional expression grid corresponding to the facial expression grid of the current frame; Input the facial expression model with the first weight coefficient and the second weight coefficient respectively to determine the facial expression grid, wherein In the facial expression model, the facial expression grid is represented by a normal expression grid, a predetermined number of linear weighted results of basic expression grids, and a preset number of linear weighted results of emotional expression grids. The method generates an emotional expression animation in a speaking process by means of an emotional expression label, which can make the animation vivid and lifelike, improve the animation effect, and reduce manual operations.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of computer network technology, and in particular to a method and device for generating virtual animation emoticons. Background technique [0002] In order to obtain richer expressions and movements, it is necessary for the virtual animation image to incorporate some special emotional expressions when speaking. For example, speaking with a smile, speaking sadly, speaking playfully, etc. In addition, we need to synthesize facial actions with multiple emotional expressions, for example, the action "smiling contemptuously" has both "scornful" and "laughing" emotional expressions. "Surprised with anger" has the two emotional expressions of "surprised" and "angry". [0003] At present, when synthesizing images, if you want to add emotional expressions in the speaking process, the following two methods are usually used to achieve: one way is to use the synthesiz...
