 note = {遺物である土器は，多くの場合が砕けた状態で遺跡から出土する．一般的には土器の分類から，組み立て，復元までを手作業で行っている場合が多い．このとき，欠落部分は石膏などを用いて人手により埋める必要がある．本稿では，破片が欠落している部分に着目して，欠落部分の周りの形状から，欠落部分を表す曲面形状を表現する手法について述べる．
本手法は，まず土器表面にローパスフィルターを施し，表面から文様を取り除く．次に，文様を取り除いた表面を利用して，穴をふさぐ曲面をフィッティングにより生成する．最後に，穴の境界を構成し，その境界とフィッティングした曲面により，トリム曲面を構成する．, In many cases, earthenware is broken and excavated from ruins. Generally, all processes from the classification of earthenware to assembly and the restoration are often done by the hand work. At this time, It is necessary manually to bury a lack part by using gypsum etc. In this paper, we propose the method for expressing the surface shape by using the shape around lack part where earthenware is missed. In our method, first of all, the patterns on the surface of earthenware is removed by using the low-pass filter. After that, the surface which is filled the hole is generated from the pattern removed surface. Surface fitting method is employed to generate the hole filling surface. Finally, the trimmed surface is composed by generating the boundary of the hole, and using
the boundary and the fitting surface.},
