Abstract: The present invention relates to a method for synthesis of a non-primary facial expression. The method comprises acquiring a facial image and calculating a shape and a texture for each of a plurality of primary facial expressions for the facial image. The method further comprises the step of generating a subject-specific model of the face including each of the primary facial expressions using the calculated shapes and textures. The method also comprises selecting an expression vector corresponding to a non-primary facial expression to be synthesised and applying the expression vector to the model to synthesise a facial image having the selected non-primary facial expression. The invention also relates to a system for synthesis of a non-primary facial expression and to a method for generating an expression look-up table.

Abstract translation: 本发明涉及非主要面部表情的合成方法。 该方法包括获取面部图像并计算面部图像的多个主要面部表情中的每一个的形状和纹理。 该方法还包括使用所计算的形状和纹理来生成包括每个主要面部表情的面部的被摄体特定模型的步骤。 该方法还包括选择与要合成的非主要面部表情相对应的表达矢量，并将表达载体应用于模型以合成具有所选择的非主要面部表情的面部图像。 本发明还涉及用于合成非主要面部表情的系统和用于产生表达式查找表的方法。
