Abstract: “Sharpness” is perhaps one of the most difficult image characteristics to quantify accurately. In this article, actual picture elements are compared with their Euclidean geometrical equivalents through the concepts which are used to describe fractal objects. A fractal object is one which possesses an extremely irregular form at all scales or levels of magnification. Although any accurately mathematically defined geometric shape can be used in conjunction with any imaging system, some preliminary experimental results are given on the image of a straight line recorded on photographic film.
