This model may be applied to study the three dimensional morphologic characteristics and changes induced by growth,orthodontic treatment and orthognathic operation.

该模型可用于颅颌面硬组织在三维方向上的形态特征及因生长、正畸矫治、正颌手术引起的形态变化研究。

The results of experiments show all improved algorithms have more better performance than unimproved and they fit the needs of medical image denosing. In total, anisotropic diffusion filtering have the best performance.

实验表明，本文提出的算法较传统算法均有性能上的提高，从整体上给予了各向异性扩散滤波方法的最佳肯定。
