在动漫制作中，一些关键帧由画师精确绘制，然后大量的中间帧由助手绘制。然而，绘制许多角色，尤其是包括面部旋转的角色，是非常耗时且需要技能的工作。在本文中，我们提出一种仅从正面图像和对角线图像（图1）生成手绘角色旋转面部的自动中间帧技术。巴克斯特[2009]介绍了使用图像变形技术生成中间帧。然而，他们的方法没有考虑体现画师的风格和笔触。因此，我们通过使用由其自身数据库训练的变形技术来体现风格和笔触，并特别引入该技术来生成旋转的中间帧面部。这个数据库包含面部图像上每个部分（右眼、左眼、鼻子、嘴巴、眉毛）的重心以及轮廓。
In anime production, some key-frames are drawn by artist precisely and then a great number of in-betweening frames are drawn by assistants' hands. However, it is seriously time-consuming and skilled work to draw many characters especially including face rotation. In this paper, we propose an automatic in-betweening technique for rotating face of hand drawn character only from a front image and a diagonal image (Fig.1). Baxter [2009] represented generating in-betweening using image morphing technique. However, their approach doesn't consider reflecting the artist's style and touch. Accordingly, we represent reflecting style and touch using morphing technique trained by his own database and introduced especially to generate a rotational in-betweening faces. This database contains center of gravity of each part (right eye, left eye, nose, mouth, eyebrow) and the contours on the facial image.
