ディジタル輪郭画像から算出されるフラクタル次元の精度について 佐藤, 輝幸 SATO, Teruyuki 野村, 由司彦 NOMURA, Yoshihiko 社団法人日本機械学会 本文データは学協会の許諾に基づきCiNiiから複製したものである 530 Image Processing Fractal Dimension Accuracy Contour Image Box-Counting Method application/pdf This paper describes a characteristic of fractal dimension measurement. The fractal dimensions are calculated from digital images based on a box-counting method. Three kinds of connections with contours are examined : the 4-nearest neighbor connection(4NN), the 8-nearest neghibor connection(8NN), and a dilated type(DT). The 4NN works very well for not only simple shapes of particles but also complicated ones. The other 8NN and DT cause greater magnitude of errors in lower resolutional images. 日本機械学会 2000-05-25 jpn journal article VoR http://hdl.handle.net/10076/8629 https://mie-u.repo.nii.ac.jp/records/8224 http://ci.nii.ac.jp/naid/110002383085/ AN00187463 0387-5024 日本機械学會論文集.
