Abstract
The solution provides a frequency distribution of a dimension of objects projected onto an image, the distribution being generated by measuring the dimension of the objects in a space in which the position of each object is at least partly free, the dimension of each object in the image depending on the position of the object. The frequency distribution of the projected objects is weighted by a weighting operation compensating for the impact of the projection in order to generate a real frequency distribution of the objects.
