Abstract

The invention relates to a method of generating and using a facial expression for a virtual image created by free combination. The method comprises steps: a facial organ or a local face is selected in a virtual image organ set as a part to form a basic virtual image; a specific facial expression is selected; and then, the organ part meeting the condition is used for replacing the organ part in the basic virtual image to enable the virtual image to meet the selected specific facial expression. The invention also provides a method of generating a virtual image organ database, thereby meeting realization requirements of the above virtual image facial expression. A small amount of image resources can be used to generate a huge amount of freely-combined virtual images for enabling a user to select a virtual image to present the individual, and the virtual image facial expression is used for showing a personal feeling or an emotion. The method is applied to various kinds of two-dimensional and three-dimensional virtual images such as a human face, a whole body, an animal, a cartoon model, and an abstract emotion face.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a method and system for generating and using expressions for virtual images created by free combination.
