摘要： An apparatus and method for generating an animation of a virtual character using video data and a limited number of three-dimensional (3D) key models of a virtual character, are provided. The video data includes a sequence of two-dimensional image frames. The key models are blended together using the calculated weights, and a 3D facial expression most similar to the 2D facial expression included in each image frame may be generated. When the above operations are performed for input video data including a sequence of image frames, a facial animation, which makes facial expressions according to facial expressions included in the video data may be created.

摘要： An apparatus and method of creating a face character which corresponds to a voice of a user is provided. To create various facial expressions with fewer key models, a face character is divided in a plurality of areas and a voice sample is parameterized corresponding to pronunciation and emotion. If the user's voice is input, a face character image corresponding to divided face areas is synthesized using key models and data about parameters corresponding to the voice sample to synthesize an overall face character image using the synthesized face character image corresponding to the divided face areas.
摘要翻译：提供了一种创建对应于用户的语音的人物角色的装置和方法。为了创建具有较少关键模型的各种面部表情，将脸部角色划分成多个区域，并且对应于发音和情感的参数化语音样本。如果输入用户的声音，则使用与语音样本对应的参数的关键字模型和数据来合成对应于划分的面部区域的面部人物图像，以使用与分割的面部区域对应的合成面部人物图像来合成整体面部人物图像。
