Study on initial position evaluation of partial matching for shape similarity assessment of round eave tile

The shape similarity assessment of round eave tiles provides crucial clues for understanding regional interactions and technological dissemination. However, many excavated round eave tiles are damaged, and only a few remain in complete shape. This study proposes an initial position estimation method suited for partial shapes that include the boundary of the inner field. A method of estimating circles from the boundary of the inner field and performing partial matching along the circumference of the complete shape is used. Experiments confirmed that a boundary of the inner field equivalent to 25% of the circle is necessary.
