ABSTRACT:
An exemplary method of segmenting an object from a structure of interest is provided. A user-selected point in an image is received. A watershed transformation is performed on the user-selected point to determine a primary object. A neighboring watershed region is added to the primary object based on region competition and a smoothness constraint to form an updated object.
