摘要

The digitisation ${bf D}(R, (a, b))$ of a real disc $D(R, (a,b))$ having radius $R$ and centre $(a, b)$ consists of all integer points inside $D(R, (a,b))$ , i.e., ${bf D}(R, (a,b)) = D(R, (a, b)) cap {bf Z}^2.$ In this paper we show that there are $4 pi R^2 +{cal O}(R^{339/208}cdot (log R)^{18627/8320})$ different (up to translations) digitisations of discs having radius $R$ . More formally, $#{{bf D}(R, (a, b)) ;|; ;a; makebox{and} ;b; makebox{vary through} ;[0,1)} = 4 pi R^2 +{cal O}(R^{339/208}cdot (log R)^{18627/8320}).$ The result is of interest in the area of digital image processing because it describes how large the impact of the object position can be on its digitisation.
