A method for determining extrema of an object with respect to a reference frame that is rotated in comparison to that of the image and the equipment that acquired it is characterized by the steps of taking a first projection of the object with respect to an axis of a coordinaate system that is rotated with respect to the reference frame of the acquisition equipment, identifying in that projection locations representing extrema of the object, and outputting those locations as indicative of the extrema with respect to the axis.
