Paper Abstract

The purpose ofthis note is to present a novel techniquefor boundary determination that incorporates both a shape prior and a local intensity profile into a geometric active contour model. The basic idea of this model is to minimize an energyfunctional, which incorporates the information ofthe image gradient, the shape ofinterest, and the intensity profile across the shape into the search for the boundary of an object. The level set form of the proposed model is also provided. Experimental results on ultrasound images are presented, which indicate that this model provides close agreement with expert traced borders. These results indicate the effectiveness ofthe incorporation ofthe local intensity profile in the model.
