NAME

       mia-2dfuzzysegment - A fuzzy c-means segmentation of a 2D image

SYNOPSIS

       mia-2dfuzzysegment -i <in-file> [options]

DESCRIPTION

       mia-2dfuzzysegment  This  program  runs  a  combined  fuzzy c-means clustering and B-field
       correction to facilitate a fuzzy segmentation of 2D image. cf D.L.  Pham  and  J.L.Prince,
       "An  adaptive  fuzzy C-means algorithm for image segmentation in the presence of intensity
       inhomogeneities", Pat. Rec. Let., 20:57-68,1999
