8-7 考古学における遺構実測図のデジタル化支援(第8部門 メディア工学3)

抄録

Vectorization process of hand-drawn measured drawings of archeological remains is one of the most time-consuming tasks for researchers. A vectorization algorithm is proposed for converting scanned raster images into vector drawings suitable for publishing. The sectional patterns on a graph paper is eliminated using Fourier Transform and vectors are extracted by connecting local extrema of pixel values.
