This project aims at prediction of patient's face after removal of facial cancer. There are varieties of cancer on the face and neck. A patient and his/her family are very conscientious of the facial appearance. Therefore it is desirable for them to know how to the appearance will be before actual operation of surgery. For the purpose, we set three research topics : (1) modeling of soft objects such as face and neck, (2) texture acquisition of patient's face, and (3) 3D facial prediction after surgery. For the first topic, we decided to employ a spring network model for simulating soft tissues because its alternative, the finite element method, requires much more computation. Here it is important to determine network structure and spring constants in the model to simulate tissue softness. For the second topics, we decided to use three camera images : a frontal and two side view images since CT images do not contain facial color. For the third topic, the post-surgery appearance is predictable by cutting the springs corresponding to the part where surgery is performed. A system has been constructed for this project. Several results were obtained and shown to doctors involved in the face and neck surgery, East Hospital, National Cancer Center. Good to excellent ratings were given to the results.

该项目旨在预测面部癌症切除后患者的面部。面部和颈部有多种癌症。患者及其家人非常注重面部外观。因此，他们希望在实际手术之前了解外观如何。为此，我们设定了三个研究主题：（1）面部和颈部等软物体建模，（2）患者面部纹理获取，以及（3）术后3D面部预测。对于第一个主题，我们决定采用弹簧网络模型来模拟软组织，因为其替代方案有限元方法需要更多的计算。在这里，确定模型中的网络结构和弹簧常数以模拟组织柔软度非常重要。对于第二个主题，我们决定使用三个相机图像：一个正面图像和两个侧视图图像，因为 CT 图像不包含面部颜色。对于第三个主题，通过切割与进行手术的部位相对应的弹簧来预测手术后的外观。已经为本项目构建了一个系统。获得了一些结果并向国家癌症中心东部医院参与面部和颈部手术的医生展示。对结果给予良好到优秀的评价。
