Abstract
Various level set techniques can be used to automatically segment the colon wall, including identifying the colon wall outer boundary. A speed image can be used during level set processing. For example, the speed image can be generated via inverting the gradient perpendicular to the segmented inner boundary of the colon wall. The techniques can be useful for determining wall thickness, which can be used to classify polyp candidates, diagnose diseases of the colon, and the like.
