Abstract:
1. A method for locating a target region in a volumetric image set, the image set comprising a plurality of voxels, each of the plurality of voxels to be assigned to at least one target class or at least one background class, the method comprising: (a) calculating an initial target class statistical descriptor for the at least one target class; (b) calculating an initial background statistical descriptor for the at least one background class; (c) assigning a class to each of the plurality of voxels for which a discriminant calculated from a class statistical descriptor for the class is a minimum; (d) reestimating a background statistical descriptor for the at least one background class; and (e) locating the target region to include each of the voxels which have been assigned to the at least one target class.
