To overcome this problem, we present a system for automatic transfer function design based on visibility distribution and projective color mapping. Instead of assigning opacity directly based on voxel intensity and gradient magnitude, the opacity transfer function is automatically derived by matching the observed visibility distribution to a target visibility distribution. An automatic color assignment scheme based on projective mapping is proposed to assign colors that allow for the visual discrimination of different structures, while also reflecting the degree of similarity between them. When our method was tested on several medical volumetric datasets, the key structures within the volume were clearly visualized with minimal user intervention. © 2013 Elsevier Ltd.||Source Title:||Computerized Medical Imaging and Graphics||URI:||http://scholarbank.nus.edu.sg/handle/10635/55172||ISSN:||08956111||DOI:||10.1016/j.compmedimag.2013.08.008|
