Shape based segmentation by level set method for medical objects containing two regions

Most of segmentation algorithms are based on the assumption of intensity homogeneity within an object. However, in many applications, the object of interest contains more than one homogenous-intensity region. Even when the object's shape is known, such object is not effectively extracted. In th...
