Abstract
There are many situations in 3D imaging applications wherein object and non-object regions with identical image properties are situated in close proximity. Although the commonly used opacity functions are adequate in capturing object gradation in these situations, the non-object regions obscure the objects of interest in volume renditions based on these opacity assignments. These obscurations cannot be removed using simple techniques except by manually masking them out. We present a method based on fuzzy connectedness principles which effectively removes the obscuration automatically. The methods are illustrated using craniomaxillofacial CT patient data for separating thin bones from skin and muscle, and muscle from skin and bone boundary. The resulting remarkable clarity of renditions are illustrated.
