Interactive segmentation of image volumes with Live Surface Export

@article{citeulike:2811083, abstract = {Live Surface allows users to segment and render complex surfaces from 3D image volumes at interactive (sub-second) rates using a novel, cascading graph cut (CGC). Live Surface consists of two phases: (1) preprocessing for generation of a complete 3D hierarchy of tobogganed regions followed by tracking of all region surfaces; (2) user interaction in which, with each mouse movement, the volume is segmented and the 3D object is rendered at interactive rates. Interactive segmentation is accomplished by cascading through the 3D hierarchy from the top, applying graph cut successively, at each level, only to regions bordering the segmented surface from the previous level.
