Abstract

The position of the limits of phases and objects to be measured on an image are defined with a given accuracy’s, due to the image formation itself, to thresholding and to digitization. This paper analyses the consequences of this and proposes a simple evaluation of the induced error on measurements. The method is based on the use of stereometric relationships. Accuracy on area fraction AA and specific perimeter LA are derived. The errors on the mean chord length LC, the mean equivalent diameter D of a single particle and a population of particles are deduced. Consequences such as the optimum resolution (pixel size) of an image containing objects to get a given accuracy of size measurements are also analysed. Some limits of the evaluation are pointed out.
