ABSTRACT:
A method for determining an image point in an object image composed of the steps of detecting an image signal made up of a series of image signal components representing respective picture elements in a radiation image, which includes an object image and which has been recorded on a recording medium. The center of gravity of the object on the recording medium is found from the image signal by weighting the respective picture elements with corresponding absolute values of differentiated values resulting from the carrying out of differentiation processing on the image signal values corresponding to the respective picture elements. A position, at which the center of gravity is located, is determined as the image point in the object image.
