为了创建被操纵的视频片段,这些提取的“纹理地图电影”现在可以通过标准的图像处理和视频编辑技术以各种方式自动改变,例如,冻结,替换或过滤纹理部分,混合来自不同来源的纹理部分或改变“纹理帧”的顺序和时间。所有对面部区域的操作只需要在参考头部和纹理上定义一次,然后可以自动应用于不同演员的不同记录,因为所有的头部模型都是相互对应的,节省了大量的手动设置工作。
For the creation of manipulated video footage, these extracted “texturemap movies” can now be automatically altered by standard image processing and video editing techniques in various ways like e.g., freezing, replacing or filtering parts of the texture, mixing texture parts from different sources or changing order and timing of “texture frames”. All manipulations to facial regions need to be defined only once on a reference head and texture for a specific experiment and can then be applied automatically to different recordings of different actors, because all head models are in correspondence to each other, saving a lot of manual setup work.
