Abstract: Volume data representing a radiation image of an object are subjected to a coarse filtering process to obtain a first classification including support type and non-support type components. An iteration of low threshold filtering steps and successive extraction and classification of connected components is performed and used to rectify the result of the coarse filtering process. A further filtering is based on the location of the connected components in the volume.
